| 摘 要： | 在地震反应分析中常采用总应力分析法,但总应力法没有考虑孔隙水压力的变化规律和液化随时间的发展过程。基于二维有效应力动力分析方法,结合Biot动力固结理论,采用自行开发的有效应力动力分析程序对某核电站导流堤地基进行液化分析,给出在地震作用下砂土层的液化范围,并计算出永久变形。所得结论可以给类似工程提供理论指导。

| Abstract: | In seismic response analysis,total stress method is adopted mostly,but variation of the pore water pressure and the development process of the liquefaction are not considered in this method.Based on the dynamic analysis method of two-dimensional effective stress,combined with dynamic consolidation theory of Boit,the foundation liquefaction analysis on the diversion dike in a nuclear power plant is performed by using the effective stress dynamic analysis program which was developed by authors.The liquefied r... |
