Shear Strenght Tests for unsaturated OC clays
Shear Strenght Tests for unsaturated OC clays
(OP)
Hi... What is your preference for verifying shear strengths for unsaturated OC clays? I think that it will depend on the type of application, but I am asking this because I have a project where a bunch of tests are required and want to give a good and practical explanation of the tests that I will be selecting. For building shallow foundations, I do unconfined compression tests since the lab reports the elastic modulus so I can use it to calculate elastic settlements. In very few occasions where shear strength controls, I have used Su from this test (Su=c=qu/2).
For slope stability, remolded samples and CU tests may be more appropriate to calculate fully softened or residual strengths.
This is a medium size warehouse. Have not started the field investigation yet, but in my area these OC clays are unsaturated medium stiff clays with SPT N-values up to 10.
Would like to know your thoughts. Thanks.

My thoughts are to correlate or test to obtain phi and c, bearing in mind that such correlations are based on saturated testing in the laboratory.

Just curious to know what is the approach of other people in this situation. Thanks !!
