| 摘 要： | 株树桥水库1990年蓄水后，大坝出现渗漏，且逐年严重。为弄清其原因，从1995年8月起，对大坝采用水下查勘、物探、钻孔等方法查漏，均未取得成效。1999年又采用水下彩色电视对大坝渗漏作进一步详查，发现是由于坝体不均匀变形和止水缺陷导致两岸周边缝及垂直止水失效所致。针对检查情况提出抢险处理措施，并根据大坝结构受力特点，对大坝进行了加固处理。目前渗漏量稳定在10 L/s以内，运行状态良好。通过对大坝结构破坏机理、渗漏原因及处理措施进行系统深入地研究，总结了株树桥面板坝破坏的原因与加固的经验，以期对我国其他混凝土面板堆石坝建设有所启示和借鉴。

| Abstract: | After impoundment in 1999,the dam seepage of Zhushuqiao Reservoir happened and became increasingly serious with time.In order to find out the seepage causes,from August,1995,all the measures of underwater survey,physical survey and hole drilling etc.to find out the seepage cause were failed.In 1999,further detail check by underwater color TV was conducted and it was found that unevenly settlement of dam body and water sealing defect resulted in seepage of periphery joint and vertical water sealing fail.Base... |
