摘　　要：通过充分研究与论证,西霞院工程土石坝段采用复合土工膜斜墙防渗,突破了现行碾压土石坝设计规范的规定。针对西霞院工程土石坝段采用复合土工膜斜墙防渗,对坝型选择及防渗形式论证、复合土工膜选型及膜厚演算、复合土工膜接缝现场焊接试验及质量检测、复合土工膜耐久性研究等进一步探讨,并根据现场实际条件对现行规范中一些参数进行了补充说明,其对复合土工膜防渗技术的推广应用和深入研究具有重要的指导意义。Through full research and discussion,the earth-rock dam of Xixiayuan Project adopted compound geomembrane inclined cutoff wall and it broke through the present provisions of rolled earth-rock dam standards.In view of the questions of the earth-rock dam of Xixiayuan Project adopting compound geomembrance inclined cutoff wall,it further studied on the selection of dam type and the seepage prevention type argument,compositing geomembrane selection and film thickness calculation,compositing geomembrane seam welding test and quality detection,compositing geomembrane durability,and supplementary explaining some parameters of the existing standards according to the actual conditions.It had significance for the compound geomembrane in seepage control technology application and in-depth study.
