ABSTRACT

There are various ways of obtaining the undrained shear strength of a cohesive soil from a pressuremeter test. They include the limit pressure method, empirical correlations, the yield pressure method, the Gibson-Anderson method, and the shear curve method. The limit pressure method makes use of the theoretical expression of the limit pressure. The yield pressure method makes use of the theoretical expression of the yield pressure. Where the tensile strength of a cemented soil or of a heavily over-consolidated clay is plotted, the break in the elastic part of the PMT curve is related to the tensile strength of the soil. he chapter also presents the correlation results for sand and clay.
