AbstractA series of field vane strength measurements conducted in the subsoil of four fills of different geometry and constructed on Champlain Sea clays near Ottawa, Canada, gave values the same as those found prior to construction. On the other hand, laboratory triaxial compression tests conducted on undisturbed piston samples taken at the same time as the vane measurements showed a definite increase in shear resistance when tested at stress conditions comparable to the effective stresses existing under the fills. The possible factors contributing to this discrepancy are discussed.
