摘要
随着各类承压洞室工程的建设,对岩体物理力学参数的测试提出了新的更高的要求。在测试系统创新发展的基础上,根据众多工程的实际应用研究,对原地应力、洞室围岩的抗劈裂能力、原地抗张强度以及岩体的高压透水率综合测试技术进行了探讨。工程建设的实践表明,岩体力学参数的综合测试是非常必要的,其测试成果是工程科学设计的依据。
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.
