Concept explainers

Test for Determination of Shear Strength

The term shear strength is often associated with the soil. Shear strength is defined as the resistance to the deformation of soil particles due to the continuous action of shear stress. In short, shear strength is the maximum shear stress that a soil can sustain.

Samples of damp sand are tested in direct shear (samples are tested at the in situ water content). The procedure involves two separate tests, with different normal loads for each test. In test one, using a normal loading which causes a compressive stress equal to 50 kPa, the sample is failed at a shear stress equal to 33 kPa. For test two, the normal stress is 80 kPa and the sample shears at a stress of 51 kPa. Use this test data to determine the angle of internal friction and the value of apparent cohesion for this sand.
A sand sample is subjected to direct shear testing at it's (in - situ) water content. Two tests are performed.
