SOIL MECHANICS II
2. INTRODUCTION
All construction projects are made on the soil.
The soil has to take the weight of the structures.
The soil testing before construction is first step and important step for all
construction projects.
Soil testing is primarily done to test the bearing capacity of the soil.
Report selected for performed test results ‘Geotechnical Investigation of 3-Day
Animal Holding Site for FML Tehsil Mirpur Sakhro, District Thatta, Sindh’.
3. TESTS FOR SOIL INVESTIGATION
The design of the foundation is based on the soil test report. Some tests are
conducted at the construction site while others are done in the laboratory.
• Moisture Content Test
• Specific Gravity Test
• Dry Density Test
• Atterberg Limits Test
• Proctor’s Test
• Direct Shear Test
• Standard penetration test
5. BORELOG
Five borehole drilled upto depth of 10m by rotary method
No Ground water table found upto 10m
Standard penetration test (SPT) was performed at every 1.0 meter interval to a depth of 10
meter in each bore. The SPT was performed as per ASTM D-1586-34.
Coring was not carried out as hard clay / rock was not encountered during drilling.
Disturbed Soil samples were collected from SPT spoon sampler. All disturbed samples were
preserved in sample bags and properly labeled.
Undisturbed soil samples were not collected as cohesive strata were not encountered.
9. DIRECT SHEAR TEST.
To determine the shearing strength of the soil using the direct shear apparatus.
The strength of a soil depends of its resistance to shearing stresses. It is made up of
basically the components;
1. Friction (angle of friction)
. 2. Cohesion
* Dense sand, Silty sands, Silty sand - Loose, Silty sand – Dense & Clayey sands
*Cohesive soils include clayey silt, sandy clay, silty clay, clay and organic clay.
1) Cohesive strength of bonding between the particles
2) Angle of internal friction (friction angle) A measure of the ability of a unit of rock
or soil to withstand a shear stress.
12. Conclusion
The same test we performed in our course ‘Soil Mechanics’. A lot of knowledge we
get from this field test report.
• Standards (ASTM)
• Borelogs
• Testpits
One interesting finding was that professional reports are colourful.
