| 摘 要： | 为了研究岩石在承压水渗流过程中影响渗透率的主要因素、裂隙的扩展规律及导致的最终破坏形式,采用MTS 815.02岩石力学电液伺服系统对岩石试件进行了实验和分析.基于岩石力学理论及断裂力学理论建立了渗流实验力学模型,对实验结果进行了合理的力学解释.实验结果表明:岩石的岩性、成岩条件、节理裂隙发育状况及受力状态是影响岩石渗透率变化的主要因素;岩石渗透率的"突变"现象在一定程度上反映了不同岩石内部裂隙发生大规模扩展时应力状态及扩展速率的差异,岩石渗流过程中裂隙的扩展贯通及最终破坏形式,不仅与岩石的岩性有关,还和裂隙与主应力的夹角及有关.

| Abstract: | In order to study the main effect factor on percolation rate of rock,the expansion rules of fractures and final failure forms,we adopt the MTS 815.02 rock mechanics battery solution server to carry out the experiment and the analysis of rock samples.Based on the rock mechanics theory and the fissuring mechanics theory,we establish the seepage experiment mechanical model and explain the experiment results in reasonable mechanical knowledge.The results indicate that the lithology,the rock creation condition,t... |
