Searching Geotechpedia for shale failure

<p>Geotechnical performance of a structure is generally governed by spatial average soil properties, such as the average shear strength along a potential slip surface in a slope. In Eurocode the characteristic soil value is defined as &ldquo;a cautious estimate ...

<p>Previous research has shown that cyclic wetting and drying can reduce the shear strength of compacted highly plastic clays to the fully softened shear strength. Consolidated-undrained triaxial testing procedures were used to determine the fully softened ...
