Statistical Description of Triaxial Shear Test Results
Any probabilistic approach to slope stability assessment requires an adequate statistical description of soil strength. Current statistical methods of strength description are unsuitable for this purpose. A statistical technique of soil strength description appropriate for the probabilistic assessment of slope stability in c', f' soils under drained conditions is developed here. The technique is applied to a set of results from triaxial strength tests on residual soil materials. Techniques for assessing the adequacy of a statistical description are discussed.
