摘要
现代水电、交通、矿山、能源及核废料处理等地下工程中,洞室岩体原地承载能力以及在工程运行状态下洞室围岩的实际透水性状等岩体力学参数,是地质勘测不可缺少的基础资料,也是科学地优化工程设计的依据。由于传统的裂隙渗透性测试技术与方法如常规压水试验已不能满足工程建设发展的需要,达不到有些复杂工程对岩体渗透性的特殊设计要求,因此,有必要进行多种形式的工程岩体裂隙渗透特性分析和研究,从而针对特定工程,选择合适的试验方法,探明其确切渗透规律,以保证工程设计的准确性和有效性。
With the development of present underground constructions such as hydropower projects, traffic engineerings, mining works, energy sources and nuclear waste treatments, the tunnels＇ surrounding rocks original carrying capacites and their actual permeabilities, etc. under project working states are the indispensable initial values of geological research; and these are also the reference for scientifically optimizing the engineering design. Because conventional measurement techniques and methods such as water pressure test do not adapt to the design requirement of rock masses permeability for complex engineering, it is necessary to carry out innovative and multiform fissure permeability tests. For a specific engineering, only using exact test method, the proper permeability can be mastered; and the accuracy and effectiveness of the engineering design can be ensured.
