摘　　要：结合云南省罗平县大麦田水库喀斯特库区补漏加固工程,选取了目前国内外广泛采用的若干种型号PE膜,进行了单一膜、膜与土工布组合、膜与土工布复合等不同形式组合下的拉伸、撕裂、顶破、渗透等多项有关物理力学性试验研究,优选出了适合喀斯特库区防渗的土工膜材料,并从中得出了土工膜的一些重要工程特性。Various types of PE geomembranes that have widely been used at home and abroad at the present time were selected to carry out test of their relevant physicomechanical properties including tensile elongation, tearing, bursting and permeability under different conditions such as single geomembrane, combination of geomembrane and geofabric as well as compounding of geomembrane and geofabric in the light of seepage control practice in reinforcing the Damaitian reservoir which is located in a karstic area in Louping County, Yunnan Province. A proper geomembrane material has been selected for seepage prevention in karstic areas and some important engineering properties have been obtained from the tests.
