Abstract

Abstract

By analyzing dumping undrained true triaxial test of excavation soil mass, it is studied the relation between generalized shear stress and generalized shear strain derived by generalized Hook. s law. Then intermediate principal stress coefficient is defined based on actual stress path and a shearing modulus. formula is also derived under plane unit elongation strain condition. The study results show that generalized shear stress has a strong nonlinear relation with generalized shear strain, and intermediate principal stress has interval effect on soil strength. The strength of soil enhances to a certain peak value gradually and diminishes gradually in the process of intermediate principal stress 2 increases from 3 to 1.
