用厂坝连接解决大坝深层抗滑稳定问题

Improvement of deep sliding stability of a gravity dam by joining plant and dam

本文以万家寨水电站为背景，研究了不同厂坝连接方式对坝体和厂房的应力、变形及深层抗滑稳定性的影响研究结果表明，考虑混凝土重力坝与坝后式厂房的相互作用后，可以提高大坝抗滑稳定性，改善坝体应力状态，并能减小由于下游尾水过高引起厂房向上游的变形．

This paper studies the influences of joining forms of plant and dam on stress,deformation and deep sliding stability of Wan Jiazhai Power Station. It is shown that the sliding stability and stress state of the dam can be improved by counting in the interaction between dam and plant. The joining plant with dam can also reduce the deformation of the plant caused by high downstream water level.
