engineering recuitment GATE CE 2023-24 Test Series Soil Mechanics and Foundation Engineering Shear Strength
A CU test was conducted on a soil sample with a cell pressure of 100 kN/m2. The deviator stress at failure was observed to be 60 kN/m2. The soil is known to have cohesion C'=0 and the angle of shearing resistance is 30o and undrained cohesion is 0 and the undrained angle of shearing resistance is 13.3o. What was the pore pressure (kN/m2) at failure?
