"A slope in an over-consolidated, fissured clay was analyzed by the Swedish Method of Slices.
Values of cohesion (c) and angles of friction (Ø) were determined by three different types of direct shear tests (undrained, drained and residual).
Factors of safety (functions of c and Ø) indicated that the direct shear test parameter gave a factor of safety approximately four times that represented by failure conditions in the field. Drained tests gave a factor of safety nearly 2.3 times the value represented by field conditions. The conclusion is made that these two tests are of limited value for slope stability analyses in stiff fissured clays.
The residual strength tests gave factors of safety values close to those represented by field conditions (1.2 and 1.1 versus 1.0 - 0.8 and 0.6 versus 1.0 for a theory modification). Further studies are required to evaluate the residual shear strength approach as a general method of analysis"--Abstract, page ii.
