摘　　要：洪家渡水电站大坝垂直水平位移计的埋设与安装采用二、三维有限元动静力应力应变分析,并与已建大坝工程观测成果相对比,共布置了11条横向垂直、水平位移计,1条纵向水平位移计。为了满足施工进度要求,洪家渡水电站大坝横向垂直、水平位移计采用"堆埋法"进行安装。实践证明,这一施工技术在缩短工期、提高施工质量、降低投入方面取得了良好的效果。The installation of the vertical and horizontal displacement meters for the Hongjiadu Hydropower Station adopts the ways of two or threedimensional dynamic and static stress and strain finite element analysis and in comparison with the observation data from the built dam projects. It layouts 11 vertical and horizontal displacement meters transversely and 1 horizontal displacement meter vertically in the dam. The installation of the vertical and horizontal displacement meters used the dumpembedded method in order to meet the construction schedule. The practice showed that such construction method is favorable to shorten the construction period, enhance the quality and reduce the cost as well.
