摘要 重力坝作为主要坝型之一在人类筑坝治水历史长河中发挥着举足轻重的作用,特别是随着我国西部水电能源建设的飞速发展,将有一批高重力坝水电工程投入建设和运营,这些大坝均位于高山峡谷之中,工程规模大,地质环境复杂,其坝与地基稳定安全问题是须长期关注和解决的关键科学技术难题。本文采用三维有限元法分析了某重力坝正常工况下的应力变形特性,对其正常工作状态和应力变形规律进行了深入分析。 Gravity dam, as one of the major dam types,plays a decisive role in the long history of human damming and water control.Especially with the rapid development of hydropower energy construction in the west of our country,a batch of high-gravity dam hydropower projects will be put into construction and operation.These dams are all located in high mountains and valleys, with large engineering scale and complex geological environment.The stability and safety issues of the dam and foundation are the key scientific and technological challenges that must be paid long-term attention and resolution.In this paper,the stress- deformation characteristics of a gravity dam under normal working conditions are analyzed by three- dimensional finite element method.The normal working state and stress-strain laws of the gravity dam are analyzed in depth.
