Abstract

The initiation of static liquefaction of unsaturated sand was studied by an extended Mohr-Coulomb elasto-plasticity hardening model. The second-order work was used to check the initiation point of static liquefaction under undrained shear. The results showed that the mechanical behavior of unsaturated sands will be changed by the compressibility of gas. The critical stress ratio at the liquefaction instability point decreases with the saturation degree.
