摘　　要：桓仁水电站开建于上世纪50年代末,处于物资和技术匮乏年代,设计与施工中存在一定的缺陷,工程质量未能达到预期[1]。为确保水电站的安全有效运行,在以后几十年当中不断投入人力、物力,对大坝进行过多次的改造和维护[2]。对桓仁大坝的坝基扬压力和绕坝渗流进行了分析和评价,结果显示除了27#坝段有一孔扬压力超限外,其他参数都在正常范围之内,由此认为桓仁坝基帷幕和排水系统运行基本正常。Huanren hydropower station was built in the late 1950 s, when the materials and technol- ogy were scarce. Some defects existing in the design and construction, and the quality of the project failed to meet expectations. In order to ensure the safe and effective operation of hydropower station, a lot of resources was used constantly In later decades for multiple renovation and maintenance. The Huanren dam foundation uplift pressure and seepage around the dam was analyzed and evaluated in this paper. The results showed that only a hole uplift pressure of the 27# Section was out of range, the other parameters were within normal range. So it is concluded that the Huanren dam foundation cur- tain and drainage system running normally.
