STUDY ON DYNAMIC STEADY STATE STRENGTH OF SAND SOIL LIQUEFACTION
砂土液化动稳态强度分析

According to the dynamic triaxial test of sand, there is a steady state at the last phase of the development of strain and stress path. In different cycle of this phase, the stress paths superpose with each other, but the axial strain tends to a steady rate. The strength of the sand in this phase is studied because it is an important parameter to evaluate the stability of sand soil liquefaction. Considering the strength developed with stress path, the mechanism of saturated sand liquefaction seems more clear.
