喀斯特地区防渗帷幕设计及施工特点

Design of Anti-seepage Curtain for Karstland & Its Construction Characters

喀斯特是水工建筑物基础常遇到的地质问题,若处理不好会引起水库渗漏甚至危及水工建筑物的安全,因此如何有效的针对喀斯特地基进行防渗帷幕设计,防止水库渗漏,对喀斯特地区水利水电工程有着重要意义。本文结合笔者的工程实践,对喀斯特地区帷幕设计的前期工作、设计要点和施工特点进行了较全面的介绍,与读者交流探讨。

Karst is a geological problem that is often encountered in hydraulic structure foundation construction. It would lead to reservoir leakage if could not deal with the problem, and even endanger the safety of hydraulic structure. Therefore it has important significance to conservancy and hydropower projects of karst areas, that how to effectively make the design of anti-seepage curtain for Karst foundation and prevent reservoir leakage. Combining with the engineering practices, the article comprehensively introduced the previous period working, design keys and construction characters of anti-seepage curtain in Karstland, in order to exchange and inquire into with readers.
