A new hollow cylinder apparatus for laboratory testing of rock joints will be used to measure the water pressure in the joints during the undrained testing of saturated rock joints. The testing program will contribute to the overall understanding of rock discontinuity behavior, particularly the role of joint water pressure and the interaction between the hydraulic properties of the joint and the mechanical response. Since the stability of rock excavations and underground structures is largely dependent upon the properties of the rock joints, applications of this research include tunnels, power plants, subterranean storage facilities, and waste depositories.

在饱和岩石节理的不排水测试过程中，将使用一种用于实验室测试岩石节理的新的空心圆柱体仪器来测量节理中的水压。该测试计划将有助于全面了解岩石的不连续性态，特别是节理水压力的作用，以及节理的水力特性和力学响应之间的相互作用。由于岩石开挖和地下结构的稳定性在很大程度上取决于岩石节理的性质，因此这项研究的应用范围包括隧道、发电厂、地下储存设施和废物库。
