摘　　要：国内外大量地下工程建设的实践表明,岩体中的不连续面对地下工程的建造与长期运行安全有重要影响,有时甚至是决定性的作用,深入研究裂隙岩体的力学和渗流特性,研究成果对指导工程实践具有重要意义。在详细总结国内外学者和作者团队在裂隙岩体力学特性的理论模型、室内试验、现场原位试验、数值仿真方法等方面研究成果的基础上,提出裂隙岩体地下工程稳定性研究的重点发展方向,并探讨裂隙三维几何表征与数值建模、裂隙岩体应力渗流耦合特性、裂隙岩体宏细观渐进破坏机制及数值仿真技术和裂隙岩体地下工程锚固机制与新技术等。The engineering practices both in China and other countries indicate that the discontinuous surfaces existing in natural rock mass have strong effects on the stability conditions of geotechnical structures and even a decisive influence. It is significant to reveal the underlying unsolved problems of seepage behaviors and mechanical mechanisms of jointed rock mass. Based on the review of a lot of research works in the problems of mechanical characteristics for fractured rock,the present work proposed the research focuses and development directions from the viewpoints of theoretical approaches,indoor test,in-situ test and numerical methods,and mainly discussed these topics as follows:field investigation techniques and generation methods of fracture network,stress-flow characteristics of fractured rock mass,macroscale and microscale progressive failure mechanisms of fractured rock mass, and anchoring techniques in underground engineering of fractured rock mass.
