三峡水利枢纽厂房坝段结构三维动力有限元分析

Three Dimensional Finite Element Dynamic Analysis for The Powerhouse Monolith of the Three Gorges Project

本计算用ADINA程序对三峡水利枢纽厂房坝段进行三维动力分析,计算了空库刚基,空库无质量弹性地基,满库刚基,满库无质量弹性地基等4种方案,各方案均算出坝体结构动力特性和动应力反应。进行了坝体抗震强度安全分析。

The three dimensional dynamic analysis using Adina program for the powei house monolith of the Three Gorges Project is described in this paper, in which the following computing conditions are included : dam with rigid foundation and empty reservoir, dam with nomass elastic foundation and empty reserwoir, dam with rigid foundation and added mass and dam with nomass elastic foundation and added mass. Also, the dynamic characteristics and dynamic response to earthquake of the dam monolith are presented and aseismic safty of the dam is estimated.
