| 中文摘要: |
| 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，利用三维有限元程序得出灰渣坝不同工况时期的稳定情况和最危险断面。 |
| 英文摘要: |
| 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. |
