Abstract:Along with the construction of various pressure tunnels,the new measurement requirement of mechanical parameters for rock mass has been brought forward. Based on the innovation of test system,the integrated in-situ measurement technique is discussed for mechanical parameters of rock mass,such as crustal stress,ability of resisting split for surrounding rocks,tensile strength as well as permeability of rock mass under high pressure. The application to various projects indicate that the integrated measurement of mechanical parameters for rock mass is quite necessary,and the test results are the sound basis for scientific design of engineers.
