摘要
与土工膜相比,复合土工膜有许多优点,不仅对膜提供加筋和保护,还可起到排水排气的作用.土石坝复合土工膜防渗斜墙铺设方向的两个原则是:接缝最短原则和拉力大的方向接缝应少原则,并针对土石坝不同坝基和施工情况,详细介绍了斜墙复合土工膜的铺设设计方法,以及施工时需要特别注意的问题.
Compared with geomembrane,composite geomembrane has many advantages,such as reinforced protection, drain and air penetration.Two principles of paving direction of composite geomembrane tilting core dam are the shortest seam and minimum number of seams in the direction of maximum stress.In this paper,to different foundations and construction situations,the paving methods are fully described of the composite geomembrane tilting core dam as well as the problems in need of special attention in the course of construction.
