THE INFLUENCE OF STRESS SYSTEM ON THE BEHAVIOR OF SATURATED CLAYS DURING UNDRAINED SHEAR

Abstract

The study investigates one phase of the overall problem of determining in situ properties, namely, the effects of stress system variables on the undrained shear behavior of saturated clays. Stress system variables refer to the direction and relative magnitude of the three principal stresses during consolidation and during shear. The report reviews and analyzes previous work in the area and presents the results of an extensive series of consolidated-undrained triaxial tests with pore pressure measurements on normally consolidated Boston blue clay prepared from a dilute slurry. The effects on undrained shear behavior of the following topics are considered in detail: anisotropic consolidation, perfect sampling, the intermediate principal stress, and rotation of principal planes during shear. These variables are shown to have a significant influence on most of the strength parameters.
