Soil shear strength meaning
Webshear strength (Equation 12.4) is most useful. For partially, drained and undrained conditions, the evaluation of excess pore pressure is often diffi-cult. In some cases, a total-stress description of shear strength may be used. One important case is the undrained loading of saturated soils, for which the undrained shear strength (s = s) can be ...
