英文摘要：

The mechanical environment of tunnel engineering function on waterfproof material is defined as the pressure,tension and pressure-tension effects. In practical engineering, the mechanical environment and the groundwater pressure have the important influence to the effectiveness of waterproof materials in tunnels. This paper puts forward the operation principles and design parameters of the simulating experimental devices for the damage mechanisms of tunnel waterproof materials based upon the analysis on the influences of the mechanical environment,groundwater pressure and waterproofing base conditions. The result can he used to direct the design of the simulating experimental devices for the research on the failure of waterproof materials under the complex effects of mechanical environment and groundwater pressure.
