内容概要

Rock and soil are the major constituent materials of the lithosphere of the earth. They are also the most widely used engineering materials. Rock and soil exhibit some remarkable characteristics of deformation and strength behavior, such as the pressure sensitivity(or pressure dependency), shear dilatancy, dependency of stress path etc.  The two phenomena of pressure sensitivity and shear dilatancy have long been known by people. However, their origin of generation is not explained rationally yet.
