STRENGTH PARAMETERS FOR PERMANENT SLOPES IN CHAMPLAIN SEA CLAYS

From consideration of the stress paths and boundary conditions generally applicable to earth slope stability problems it is concluded that long term slope stability analyses should not be based solely on strength data obtained from strain controlled drained triaxial tests (cid or cad tests). In particular it is shown that the brittle, time dependent, and anisotropic strength data obtained from such tests on champlain sea clay may not be relevant to slope stability problems. Appropriate sampling and testing procedures, design factors of safety, and the possibility of progressive failure are discussed with reference to documented field observations.(a) /TRRL/
