摘　　要：复合土工膜因其抗拉强度高、防渗性能好和变形能力强的优点被广泛应用于库区、坝体、人工湖、蓄水池等建筑物的整体与局部防渗加固中,但对其耐酸碱腐蚀性能的研究较少.钻井废液多为腐蚀性液体,对复合土工膜的耐腐蚀性能要求更高.通过对复合土工膜酸、碱试样进行拉伸强度、梯形撕裂强度及CBR顶破强度等进行试验研究,并与干试样的试验结果进行对比分析,确定复合土工膜耐酸碱性能,为其在钻前工程全装配式废水池中的应用提供理论依据.With its high tensile strength,good anti-seepage performance,and strong deformation,geomembranes are widely used in reservoir areas,dams,artificial lakes,reservoirs,and other buildings for whole and partial seepage and reinforcement,but few studies on the acid and alkali resistance properties are seldom reported.The waste liquid of drilling is corrosive and a higher corrosion resistance is required for geomembranes.Through tests on the tensile strength,trapezoidal tear strength,and CBR bursting strength of acid and alkali geomembrane samples and comparisons with the test results of dry geomembrane samples,the acid and alkali resistance properties are determined,which provides a theoretical reference for the application of fully assembled structures in waste water pools.
