灰渣坝抗震稳定性的三维有效应力动力分析

3-D dynamic effective stress analysis on the aseismic stability of fly ash dam

本文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 .抗震分析中同时考虑了坝体的三维特性、震动引起的孔隙水压力对材料剪切模量的影响 。

In this paper, the stability of fly ash under 8 degree earthquake is studied by using 3\|D dynamic effective stress analysis method. In the analysis, the 3\|D characteristic of the dam and the influence of vibrating pore water pressure on the material shear modulus are taken into account. The stability situation and most dangerous section of the dam during earthquake in different stages of construction are derived.
