摘要
非贯通裂隙岩体是石油、采矿、水电、公路、铁道、核废料处理等各种行业岩体工程中最常见、最重要的介质之一。开展非贯通裂隙岩体力学性质研究是认识、利用、改造非贯通裂隙岩体的前提,而非贯通裂隙岩体表现出的力学性质与其破坏模式、破坏机制有着决定性的联系。从非贯通裂隙岩体的结构出发,研究其破坏模式是深入研究非贯通裂隙岩体力学性质重要途径。基于非贯通裂隙岩体结构的特点,总结前人对非贯通裂隙岩体破坏模式研究成果,试图对当前的研究手段、分析角度、研究结论等进行归类、分析、总结、思考,指出当前对非贯通裂隙岩体破坏模式研究存在的主要问题,并进一步地提出解决问题的思路与方向。
In petro-industry,mining,hydroelectric engineering,express way,rail way,and nuclear waste disposal,nonpenetrative fractured rock mass is one of the most important and common materials.The full understanding of fractured rock mass property is the first and the most important thing in order to know it,to use it,and to improve it.In most cases,failure mode of fractured rock mass is dominated to its property,so it is important to study and research it.Based on the failure mode and the structure of the fractured rock mass,which are critical for understanding its property and characteristics deeply are studied.According to the structure of fractured rock mass,the research results are achieved by the former scholars or drawn from literatures,studying methods,analytical perspective;the merit and the disadvantage of physical and numerical model tests and site experiments are discussed,the key issues in researching work are pointed out,and the solution plan is made out.
