大型调压室的结构及其应力分析

结合某水电站大型预应力钢筋混凝土调压室的设计，本文进行了调压室井壁和底板的轴对称有限元计算，并讨论了并壁与底板的连接方式；为了研究塔壁扶壁处的局部应力分布，对塔壁进行了三维有限元分析。

Structural Analysis of a prestressed Surge Chamber

In this paper,combined with the design of a prestressed concretesurge chamber in a large scale hydropower station,the stresses of thewall and bottom plate of the chamber are calculated by using the axsy-mmetric finite element,and a method to reduce the stresses at bottom of the wall is suggested.The local stress at the anchorage of theprestressed bar in the tower wan is investigated using three dimen-sional finite element in which the non-uniform disttibution of the pre-stress and the position of the anchorage of the bar are considerd.
