【Abstract】 The steady state strength theory is significant in earth structure aseismatic study. The steady state strength concepts,the consolidated-undrained triaxial shear test method and the test results are introduced. From the test and analysis,the existence and uniqueness of steady state line are demonstrated;and the steady state line equations are derived. An approach to determining the steady state strength qss from consolidation pressure σ3 and relative density Dr is presented;and the physical implication of steady state friction angle is revealed.更多还原
