土工薄膜防渗系统的应用越来越广泛,尤其是水利工程(如大坝、水库和运河)及废物贮存中心。对于这些工程以及在边坡采用土工合成材料防渗系统,“土工材料复合层”形成防渗系统护层(植被,砾石混合料,堆石,混凝土铺砌块等)的最有利的滑动面。在大多数情况下,边坡坡度太陡以致护层不能保持自稳定;这时就要通过基础翼墙和/或在边坡坡顶锚固土工合成材料确保其稳定性。近年来,波尔多集团与其合作伙伴海洋河流技术研究中心(CETMEF)、Bidim-Geosynthetics和Siplast-lcopal合作,在Cemagref对这两种构件的设计进行了研究。
Geomembrane seepage control system is more and more widely used, especially water conservancy projects (such as dams, reservoirs and canals) and waste storage center. For these projects as well as the use of geosynthetic seepage control systems on slopes, the most favorable slip of the “impermeable system cover” (vegetation, gravel mix, rockfill, concrete paver, etc.) surface. In most cases, the grade of the slope is so steep that the cover can not remain self-stabilizing; at this point, the stability is ensured by the foundation wing and / or the anchoring of geosynthetics at the top of the slope. In recent years, the Bordeaux Group, in collaboration with its partners Ocean River Technology Research Center (CETMEF), Bidim-Geosynthetics and Siplast-lcopal, has studied the design of these two components at Cemagref.
