Soil Mechanics and Foundation A normally consolidated clay settled 10 mm when effective stress was increased from 100 kN/m2 to 200 kN/ m2. If the effective stress is further increased from 200 kN/ m2 to 400 kN/ m2, then the settlement of the same clay is 10 mm 40 mm 20 mm None of these 10 mm 40 mm 20 mm None of these ANSWER DOWNLOAD EXAMIANS APP
Soil Mechanics and Foundation A 600 mm square bearing plate settles by 15 mm in plate load test on a cohesionless soil under an intensity of loading of 0.2 N/ram2.
