摘　　要：文中探究了不同防水卷材及卷材粘贴处理方式对地下连续墙抗渗效果的影响。结果表明:相比于传统自粘型防水卷材,粘贴CPS高分子防水卷材提高了混凝土试件的抗渗性能;采用卷材专用胶对混凝土试件表面进行处理后,粘贴CPS高分子防水卷材的混凝土试件抗渗等级由P6提升至P10;地下连续墙的单位时间渗水量随着水头高度的降低呈现出先增大后减小的趋势主要与卷材局部脱落面积有关。In this paper,the influence of different waterproofing membrane and membrane pasting methods on the anti-seepage effect of diaphragm wall is explored.The results show that compared with the traditional self-adhesive waterproofing membrane,sticking CPS polymer waterproofing membrane improves the impermeability of concrete specimens.After the surface of concrete specimen is treated with special glue for coiled material,the impermeability grade of concrete specimen with CPS polymer waterproof coiled material is increased from P6 to P1o.With the decrease of water head height,the water seepage per unit time of diaphragm wall increases at first and then decreases,which is mainly related to the local shedding area of coiled material.
