引言进行液化势分析时,必须考虑土为二相系(若为部分饱和土则为三相系),同时必须考虑因循环剪应变导致产生体积应变的趋势。本文中提出的数值分析法是用以计算象土坝这样的二维体系的液化势的。在整个坝体中的剪应力和剪应变根据Biot(1962)的理论来确定。可能的塑性体积应变是与应用 Introduction When performing liquefaction potential analysis, it must be considered that the soil is a two-phase system (if it is a partially saturated soil, it is a three-phase system), and the volumetric strain caused by the cyclic shear strain must be considered. The numerical analysis method proposed in this paper is used to calculate the liquefaction potential of a two-dimensional system such as an earth dam. Shear stress and shear strain throughout the dam are determined according to the Biot (1962) theory. Possible Plastic Volume Strain and Application
