摘　　要：洪家渡水电站大坝垂直、水平位移计布置时采用二、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 ,布置了 1 1条横向垂直、水平位移计 ,1条纵向垂直、水平位移计。由于对施工干扰影响大 ,洪家渡水电站大坝横向垂直、水平位移计采用了“堆埋法”进行安装 ,结果比较成功。文中介绍了其工艺流程。Vertical and horizontal displacement meters are very important instruments for dam observation. Based on two and three dimensional dynamic and static stress and strain analysis, 11 strips of transverse vertical and horizontal displacement meters and 1 strip of longitudinal vertical and horizontal displacement meters are laid out in the dam body at Hongjiadu Hydraulic Power Station. Because of the influences of construction, a favorable way for installation is extremely necessary. The dump embedded method for installation of transverse vertical and horizontal displacement meters at Hongjiadu Hydraulic Power Station is successful. This paper introduces its technological process, operation and effect.
