AbstractThe true cohesion of an undisturbed, sensitive clay was measured by compression testing of laboratory specimens at very low effective stresses. On the basis of modern ideas, the measured cohesion may be visualized as a frictional resistance mobilized by the arrangement of, and the intrinsic stresses between, individual soil particles. This concept, supported by observed fracture patterns in the laboratory and in the field, is considered to lead to a better fundamental understanding of the strength of undisturbed clay. Extrapolation of strength theories developed for remoulded clays to the assessment of undisturbed, sensitive clays is refuted.
