采用三维有效应力动力分析方法 ,分析研究了某灰渣坝在 8度地震作用下的稳定性。分析中同时考虑了坝体的三维特性以及地震荷载作用下孔隙水产生、扩散、消散作用对材料剪切模量和坝体滑动稳定性的影响 ,利用三维有限元程序最终得出灰渣坝不同时期的稳定情况及最危险断面
The 3D dynamic stress analysis method is used to analyze the stability of an ash dam under the action of 8 degree earthquake. In the analysis, considering the three-dimensional characteristics of the dam and the influence of pore water production, diffusion and dissipation on the shear modulus and the sliding stability of the dam under the action of the seismic load, the three-dimensional finite element program Period of stability and the most dangerous section
