土工合成材料在大坝防渗与导渗中的应用

Application of geosynthetic used for seepage control and diversion of the dam

土工合成材料问世已有30 a的历史,在国内外应用广泛,发展迅速,该材料具有质量轻、抗拉强度高、不易 腐烂、制造运输简便、施工速度快等优点,在水工建筑物的大坝、渠道、防洪堤、围堰等工程中得到广泛应用。文章阐 述了土工合成材料在堆石坝及病险库加固中进行坝面防渗所取得的成功经验。

There have been 30 years since the geosynthetic came out. With quick development, the geosynthetic is applied widely for various projects both at home and abroad. It has a lot of advantages with light weight, high tensile strength, non-rottenness, easy manufacture and transportation as well as quick construction. It is widely used in the dam, channel, flood dike, cofferdam of hydropower projects. The paper remarks the geosynthetic has been applied for anti-seepage of the dam face in the consolidation of rockfill and dangerous dams, and it obtains successful result.
