摘　　要：岩体中节理裂隙的存在是影响岩体宏观力学性能的关键因素。岩体因节理面诱发的破坏(剪切、拉伸及复合型破坏)是一种非常常见的工程灾变形式,因此开展不同应力、温度、加载速率等条件下含节理裂隙岩体力学特性的研究具有重要的科学意义和工程意义。前人针对节理裂隙岩体的力学特性开展了大量的研究工作,并取得了丰富的研究成果。近几年随着测量方法、试验技术等的发展和生产需求的变化,出现了一些新的研究方向(如高应力、高温度、冻融循环、高速冲击荷载下节理力学特性),发展了一系列新的测试分析方法(如DIC技术、CT扫描、激光扫描、声发射高精度定位、3D打印、3D雕刻),并涌现出众多新颖的研究成果。从节理裂隙岩体力学特性的研究方向、研究方法和研究进展等方面做了详细总结,着重论述了在节理裂隙力学特性的室内试验方面取得的一系列研究成果,并且分析了目前研究内容所存在的不足,对促进人们对不同环境下节理裂隙力学特性的理解、指导相关科研人员开展后续的节理裂隙力学行为研究具有重要的参考价值。The existence of joints and fractures in rock mass is a key factor affecting the macroscopic mechanical properties of rock mass.The shear,tensile and composite failures of rock mass induced by joints are a very common form of engineering disaster.Therefore,it is of great scientific and engineering significance to study the mechanical properties of jointed rock mass under different stress,temperature and loading conditions.Numerous researches on mechanical properties of jointed and fractured rock mass have been conducted,and abundant research progress have been obtained.With the fast development of testing methods and measuring techniques,some new research directions such as high stress,high temperature,freeze-thaw cycle,and mechanical properties of joints under high speed impact load have emerged,and a series of new test and analysis methods such as DIC technology,CT scanning,laser scanning,AE high-precision positioning,3D printing,3D engraving have been developed and the research achievements have been discovered.In this paper,the research branches,methods and progress of mechanical properties of jointed and fractured rock mass are summarized in detail,and the research findings from laboratory studies on jointed and fractured rock mass properties are particularly reviewed.The shortcomings of the present research are also analyzed from different aspects.The present study will contribute to the deep understanding of the jointed and fractured rock mass properties under different and complex conditions,and will also provide valuable guidance for further studies on the jointed and fractured rock mass properties in the long run.
