We are pleased to present the soil test, soil boring test and recommentdation about foundation design by senior civil engineer teams with more than 10 years experience.

Soil Test and Soil Boring Test Soil Boring Test The structures will be stability and safty, must be supported by indissoluble foundation and also foundation design should be safe enough.

Soil test and soil boring test is very important. The enables engineer to design a safty foundation by foundation engineering method and construction cost savings.

Normally the price of soil boring test should be between 0. Scope and details of soil boring test depends on the qualities of the project and soil condition. Civil Engineer must be assignment the details of soil boring test so that to have the data essential for analysis and design.

Sub soil conditions in various areas of thailand may have a variance so that the area is different from the general area such as very loose sand, soft clay layer or depth of soil is strength and high variability, etc.

This could be the cause of the failure of the foundation that causing unpredictable damage. Therefore the good project owner should focus on soil test for designing various buildings is circumspect and invalid by engineering method. Soil Test For a small sum you can protect, possibly, the largest investment of your life. Without the right foundations, buildings can move and walls can crack.

Why risk the expense for the cost of a soil test? Problems can be discovered prior to purchase or building. Being aware of any problems will enable you to determine future costs and help you to make vital decisions about the suitability of the land for building.

This is a better alternative to finding problems after purchase of land or after building has commenced. About Soil Test A Drill Rig and other equipment are used to collect information and samples at various levels on the site. Samples are taken to the laboratory for testing.

A detailed report and summary of data is prepared. This is used by the engineer to design the foundations in accordance with Australian Standards. This design will match the site conditions, give you peace of mind yet will reduce the risk of over design thus saving you money.

More about Soil Test Soil Test is an essential part of foundation design. Foundations are vital to the integrity of every structure being the interface with the soil or rock below. Soil has a variety of properties which can vary from place to place and from layer to layer even within the limits of the proposed structure. At times soil characteristics can change considerably within a small area.

Weather, climatic changes, and site management can, in the future, affect the bearing qualities of the soil. Putting it simply, if the foundations are not designed to the carrying capacity of the soils then they will fail and so will the building. Important design considerations are bearing capacity and settlement. Obviously the foundations must be able to support the considerable weight of the building. The soil or rock below must then bear the entire weight.

Settlement may occur at different rates in different sections of the foundations. Other considerations include the ability of clay to shrink and swell with changes in moisture, eg from climatic changes, penetration of surface water or the effect of vegetation absorbing water.

Investigation of the site is limited due to economic and time constraints. A soil investigation should always be used as a guide only, to give a general indication of sub surface strata, its approximate surface movement and its capacity to bear the proposed construction for the site. The design engineer should relate this report to the specific needs of the construction proposed for this site and if further information is required, should treat this report as preliminary and request a more in depth investigation.

This report is based on site information as at the time of investigation. If after excavation of the site footings, the soil profile is significantly different to that indicated on the attached borelogs, or if the building is situated in a different location to that marked on the site sketch or if any material change has occurred to the site, this report will become void.The depth of soil affected by the load transmitted by the foundation determines the required depth of boring in the overall process.

Considering the effect of stress felt, the boring should be always taken to a depth at least equal to one and half times of the foundation width below the base of the foundation. The depth of boreholes to be made under different foundation conditions are shown in Fig 1, 2 and 3.

A detailed record of boring operations and other tests carried out in the field is an essential part of the field work. The bore hole log is made during the boring operation. The soil is classified based on the visual examination of the disturbed samples collected. A typical example of a bore hole log is given in Table 2. Greyish sandy silt medium dense. Greyish silt sand dense. Blackish very stiff clay. Introduction to Depth of Boring: The depth of soil affected by the load transmitted by the foundation determines the required depth of boring in the overall process.

I have been doing drilling observation for a few years and I have been trying to figure out how to interpret the boring logs I create and make recommendations for Geotechnical Reports.

Right now I am trying to figure out how to determine the allowable bearing capacity for shallow foundations. I got a boring log and converted the N values to N60 values.

bore log profile in foundation engineering

Then I was going to use Terzaghi equations for ultimate bearing capacity. The problem is I can't figure out what to use for densities or friction values off the boring logs. First, the relative density doesn't give me a density in pcf, only as a percent. Do I just interpolate?

And can I use the relative density for a SM soil, or does it have to be a clean sand? What do I do if I have a clay or silt?

I think I can get the friction angle, I think I just need densities to get overburden stresses. I'm trying to self teach this to myself. I just don't know where to start. I have been on Google all day. I found some things from the US Navy, but didn't find it helpful. Does anyone know somewhere I should start? Like books, specs, manuals, whatever?

I don't mean to be flippant; however, you start with an engineering degree with a heavy emphasis in geotechnical engineering. But I'm stuck right now as an Engineering Technician. And my office doesn't have time to train me, so I am trying to learn on my own. I'm trying to find out where to find what to do with the data from the boring logs.

Can anyone point me in the right direction? I applaud your desire to learn.The internal diameter of a sampler is 50 mm and the external diameter is 52 mm. Discuss the sample obtained from the sampler as disturbed or undisturbed?

Related Articles.On practically every construction project involving soil, whether excavating, moving or building atop, there is usually a geotechnical investigation. The report is financed and commissioned by the owner and project design engineer for the purpose of obtaining soil properties relative to structural stability and longevity of the project.

The basic exploratory program most often consists of bore hole drilling and sample recovery, testing of the bore hole, visual and manual testing to classify the soil in accordance with the Uniform Soil Classification System, and further laboratory testing of samples taken from the drilling program.

From the testing program and research regarding the geological setting, current history of the site, seismicity, hydrology and chemical analysis from potential contaminated sources a geotechnical report, including design recommendations, is developed.

The primary purpose of the soils report is to provide information for the design and longevity of the project being constructed. The report generally looks at a timeline of years or more and encompasses permanent structures that will be in place over that time.

One secondary purpose of the soils investigation is to gather constructability and shoring applications design information. The excavation and shoring work period usually ranges from about 2 months to 1 year, with the system s installed, removed and backfilled over that time period. The geotechnical engineer is typically most focused on the primary report featuring the design and longevity of the site.

The extension to shoring, and even dewatering applications, is typically performed by the contractor, a shoring design engineer and or a dewatering engineer as appropriate.

This article provides a general framework on how a contractor may read a soils report to extract this information. Our analysis will begin with the bore log Figure 1.

CE6502 Foundation engineering previous year question papers

The bore log provides us several key pieces of information including:. From my own personal experience, I find the most direct way to determine soil type is to read the material description. For cohesive soils the terms soft to hard, as shown in the first column on Table 1-Cohesive Soils are always contained in the description of each layer and for non-cohesive soils the terms very loose to very dense as shown on Table 2-Non-Cohesive Soils are always contained in the description of each layer.

These terms are always used with their respective soil types and never interchanged, although notes about clay or sand may be included. Another way to determine the soil type is to look at the classification in the descriptionmost often in parenthesis like GP-GC or CL ; however, the user would then have to look at the uniform classification table to determine whether it is in the cohesive or non-cohesive division.

Determining soil type is fundamentally important because clays behave much different than sands and gravels and effects virtually every shoring decision. One decision strictly based on soil type is that for cohesive soils dewatering can generally be achieved from sumps inside the excavation and for non-cohesive soils dewatering may require dewatering from wells outside the excavation. There is a significant cost difference between these two dewatering scenarios. Further examination of the soil classification can parse this out much closer but is not discussed in this article.

Water table level is also fundamental information. The extent of dewatering required has a significant impact on the cost of dewatering and shoring. In the bore log the level is usually indicated by a small triangle or an upside down Greek delta D.

It is also usually called out in the heading as ground water at time of drilling and ground water at some later date. If there is no reference to water in the bore log the general assumption would be that there is none. The blow count is taken at the time of drilling An SPT sampler is a hollow tube set on the end of the drill string.

There is a trip hammer at the rig that drives it down. The test is performed by marking the drill string at the rig and counting the blows it takes to advance down every 6 inches. When the tube is pulled out the sample inside it can be retrieved and analyzed. Blow count readings simply provide a scale of how hard the soil is to penetrate. The blow count unit of measure is represented as a lb hammer drop over a in fall.

Looking at the bore log shown in Figure 1, the Blow Counts Field Value is shown in the fifth column from the left. This is a strict reading of the number of drops. Table 5. At the bid stage and first reading I do not suggest going through these corrections; however, at the shoring design stage it should be checked out closer.

The objective here is to get a quick contractors read of the bore log to glean the necessary information for bidding and shoring application decisions. The blow count is the single most important piece of information needed to determine the strength of the soil.
