Homeworks of chapter 5 2.The effective stress parameters for a fully saturated clay are known to be c= 15 kN/m² and o'=30° . In an unconsolidated- undrained triaxial test on a specimen of the same clay the all-round pressure was 100 kN/m² and the principal stress difference at failure 170 kN/m?. Assuming that the above parameters are appropriate to the failure stress state of the test, what would be the expected value of pore water pressure in the specimen at failure?

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.
