复合土工膜或土工膜堤坝实例述评

Review of Dams and Dikes with Composite Geomembrane Impervious Structure

列举了有代表性的、有参考价值的国内外一些采用复合土工膜或土工膜防渗的堤坝,其中有新建堤坝8座、病险坝加固补强5座、大江大河施工围堰2座,建成时间最早的是1972年,最近的是1999年.针对这些堤坝的剖面形式和构造特点,对其优点和不足之处作了评述,以便在今后的工程应用中取其优点,避其缺点,求得技术进步.

In this paper,several representative domestic and abroad dams and dikes with composite geomembrane impervious sheet were illustrated.In which,8dams were built recently,5were faulted dams repaired with composite geomembranes,2were cofferdams on the large river.These projects had been finished between1972to1999.The structural sections and characteristics of these dams and dikes are described in this paper.Some designing and constructional defeats of these dams and dikes are criticized in order to raise the technique level of composite geomembrane dams and dikes.
