Abstract

The purpose of this paper is to develop a mathematical model for the evaluation of liquefaction characters for soil subjected to earthquake induced cyclic loading. Cyclic triaxial test results are used to develop the basic model. It is then used to evaluate cyclic shear strength τR, number of cycles required to cause liquefaction Nι or failure condition Nf , and the generation of excess pore water pressure Ug. The development of this model is a great breakthrough for the evaluation of liquefaction characteristics for soils under earthquake loadings.
