摘要
本文描述了复合土工薄膜的选择原理,针对李宋箐土坝的具体情况作了合理选择,并进行了室内技术论证。1987～1988年间,在上游坝面铺设复合土工薄膜17800m^2,从防渗应用来看,达到了预期的效果。
This paper presents mainly the conception considerations with regard to the choice of impervious materials properties, the structure of impervious lining system and the results of tests in laboratory. In 1987-1988, 17800m^2 of geomembrane composite was installed on the whole upstream slope. At present the extended dam is in normal operation, the observed results for seepage discharge agree well with the value calculated.
