Further Discussion on Seepage Control Technique with Geomembrane in Xixiayuan Project

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.
