广西澄碧河水库大坝防渗加固设计

Analysis on stress-deformation of diaphragm wall for the dam of Guangxi Chengbi river reservoir

澄碧河水库大坝中已有混凝土防渗墙防渗,但由于运行多年,防渗墙质量存在缺陷,防渗效果较差,须进行防渗加固,根据澄碧河水库大坝的具体情况,对大坝存在的渗漏问题进行了分析,提出了相应的防渗加固措施,加固效果明显,为已有防渗墙的土坝防渗加固设计提供了参考。

The dam of Chengbi river reservoir has a concrete diaphragm wall,but it has quality defects because of operating so many years. The seepage prevention is becoming less effective,so have to reinforce the anti-seepage system. According to the specific conditions of the dam of the reservoir,the seepage problems of the dam are analyzed,the corresponding anti-seepage reinforcement measures are put forward. The reinforcement effect is obvious. Offers a reference for the application to reinforce the anti-seepage system of the earth-dam which has the old diaphragm wall.
