Abstract

The concept of liquefaction strength curve, which is often used for description of the possibility for liquefaction of loose sand in practical design, is tried to be applied for the simulation of the cyclic softening behavior of volcanic clayey soils during earthquake. The method of drawing a liquefaction strength curve based on the UW softening model with the total stress formulations is proposed here. The relationships between the input material parameters in the model and the curvilinear shape acquired is clarified. The obtained results can be useful for future development of numerical applications with the elasto-plastic finite element method to the landslide simulations.
