摘　　要：通过复合式衬砌防水层工作性态模拟试验 ,发现隧道防水层基面喷射混凝土表面的粗糙度对防水层的长期完好性有至关重要的影响。在试验基础上 ,分析了防水层的压缩和剪切变形特性 ,探讨了压剪强度规律 。Through simulating tests on working behaviour of water proof layer in composite linings of highway tunnels, it is discovered that the roughness of the base for the water proof layer——the surface of concrete seriously affects the working condition of the layers during their long time service. Based on the tests,pressure deformation and shear deformation curves for the layers are established,and the shear strenthes are discussed as well. Meanwhile some suggestions for the design and construction of water proof layers in highway tunnel are presented.
