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 s3 and relative density Dr is presented；and the physical implication of steady state friction angle is revealed.
