摘要

本文在建筑物地基地震液化总应力简化判别方法的基础上，考虑地基土壤的剪切非线性及饱和砂 土Ｍａｒｔｉｎ非线性孔压增长模型，提出了估计建筑物地基孔压增长的简化分析方法，这一方法可用来判 别地基的初始液化问题。
In this paper, based on the simplified method of total stress for seismic liquefaction of building's subsoil and combined with nonlinear constitutive relationship of soils and Martin's model of pore water pressure, a simplified method is suggested for evaluating pore water pressure of building's nonlinear subsoil. The method could be applied to analyze liquefaction potential of subsoil of building, directly in terms of pore pressure ratio.
