| 摘 要： | 本文对印度柯依那重力坝进行了随机地震反应分析.首先用一非平稳的随机过程来模拟1967年12月11日地震时的地面运动加速度,并提出了一个基于有限单元法的重力坝地震可靠度分析方法,计算结果对坝体裂缝的成因可作出较为合理的解释.

| Abstract: | A new non-stationary random process for the simulation of ground accelaration of the eleventh of Dec. , 1967 Koyna earthquake is suggested. A method for the analysis of stochastic earthquake response and the reliability of Koyna Dam is presented. This method is based on the finite element method. The numerical result can give a reasonable explanation for the formation of crevices in the dam. |
