Abstract

"The investigation was undertaken to determine shear strength and pore pressure parameters of a soil when subjected to sequential loading. This method is intended to similate the in-situ condition of stress application under certain field conditions. The testing procedure, a sequential triaxial shear test, is described. This test consists of successive stages of partial consolidation followed by undrained shear. Triaxial consolidation and shear strength characteristics of a sedimented remolded silty-clay are compared with the results from conventional tests on isotropically consolidated samples. The undrained strength was found to be a function of moisture content, irrespective of the method of test and initial stress system for the normally consolidated soil. A unique relationship was established between a pore pressure parameter, the ratio of the change in pore pressure to the effective vertical consolidation pressure, and undrained strength. It is concluded that this sequential procedure of testing does change the strength characteristics of the soil. These cannot be predicted from the conventional test"--Abstract, page ii.
