Question

Differece between effective and aparent cohesion

Answer 1

The above assertion is truly based on laboratory tests. Generally, normally consolidated clays (existing stresses are equal to the max. past stresses) are obtained for the remoulded samples, where the soil got disturbed and the stress history of clays has been destroyed and the present stress itself a max. past stress. Since we run tests on remoulded samples which are fully softened, it will have no cohesion but angle of friction.
