水电站厂坝联合作用的受力特性分析

Analysis on the Stress Characteristics of Combined Action of Powerhouse and Dain for Hydropower Station

本文结合我国某水电站厂，坝间分缝主不设分缝的厂坝联合作用形式，用空间有限元法研究了在各种运行条件下的变形及应力分布规律，探明了该为结构的空间整体受力特性为水电站的合理结构设计提供了可靠依据。

Abstract According to the combined action structure in which there is no slit bewteen the powerhouseand the dam in some hydropower station of our country,this paper discusses the rules of deformationand stress distribution under all kinds of working condition by using three-dimensional finite elementmethod.It studies the stress characteristics of this kind of whole structure in three dimension to providereliable basis for reasonable structural design of hydropower station.Deseriptors Dam,Powerhouse,Mechanical model,Analysis
