Abstract [en]
Presents results from the piezocone tests in a study focusing on the influence of the horizontal stresses on the undrained shear strength measured with both piezocone and field vane shear tests in clay, with special reference to clay slopes. The influence of the horizontal stresses was studied by model tests with a mini piezocone in large triaxial cells. The shear strength evaluated in the model tests has compared with an empirical equation that describes how the undrained shear strength varies with preconsoiidation pressure and overconsolidation ratio and with results from direct simple shear tests. In addition, the undrained shear strength at the toe of a slope has been predicted based on the results of the model tests together with piezocone tests above the crest of the slope.
