摘要

在分析建筑物地基的地震（或振动）液化时，为了简化分析土壤-地基的动力相互作用，引入Cone模型，在总应力分析的方法基础上，结合了Martin等提出的孔隙水压力发展模型，并且考虑土壤发生液化的动力非线性过程中材料刚度退化的影响，提出了可以直接求解各区域的孔隙水压力的有效应力简化分析法，并进行液化可能性判别。

Abstract

The modulus degeneration of sand is thought as one of characters of dynamical nonlinear to analyze the seismic liquefaction of subsoil of building. Based on the total stress method

a cone model theory by Wolf and Meek

combined with the model of pore water pressure generation presented by Martin

is introduced to simplify the interaction of soil-structure and calculate the dynamical stress field of subsoil

so that pore water pressure under the building can be evaluated directly

an effective stress method is suggested to evaluate liquefaction potential of building’s subsoil.
