WebThe undrained bulk modulus and Poisson’s ratio were larger than their drained counterparts. Calculation of the unjacketed bulk modulus (28.9 GPa) showed that it is smaller than that usually taken for sandstones quartz grain bulk modulus (36 GPa). Webpartially, 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 used. This is the common 4) = 4 = 0 analysis
WebA reliable estimate of secant undrained Young’s modulus (E u) is necessary to quantify the undrained settlement of structures underlain by fine-grained soils.A large number of CK 0 UC triaxial tests have been carried out on eight resedimented clays to establish the effects of soil composition, applied shear stress, overconsolidation, and vertical consolidation … Webmethod that is best suited to model the loading condition (undrained total stress or drained effective stress) and the soil response. Shear strength laboratory testing methods are described in Section . 200D-1. The selection of peak, fully softened, or residual shear strength for design analyses should ...
