摘　　要：隧道工程对防水材料作用的力学环境是指衬砌变形等外力产生的压力、拉力及拉-压力。实际工程中,隧道的力学环境和水压共同作用,对防水材料的防水效能有重要影响。在对隧道力学环境、水环境、防水材料基面条件等影响因素分析的基础上,提出防水材料损伤机理的模拟实验装置工作原理及设计参数,为分析在力学环境、水压综合作用下防水材料失效效能的模拟实验装置提供设计依据。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.
