Abstract
The results of undrained direct simple shear tests (DSS) on peat samples taken for a motorway investigation in the Netherlands are studied and compared with these from undrained triaxial tests. A numerical model of the test using the finite element program PLAXIS showed that the horizontal and vertical effective stresses were approximately equal at failure. This implies that for c'=0, then φ'~Sin-1 (τ/σ(v)')(max). This relationship is shown to give a reasonable estimate of φ' for peat when compared to that obtained from other tests.
