摘要
针对裂隙对类岩石力学性质的影响,阐述了近年来关于含裂隙类岩石力学性质方面的研究进展,主要包括不同裂隙数目、裂隙倾角和裂隙形状下裂隙类岩石的力学特性。通过对预制裂隙类岩石试件的深入探究,系统分析了在单轴压缩试验、双轴压缩试验、三轴压缩试验以及数值模拟中含裂隙类岩石试件的力学特性。此外,介绍了含裂隙类岩石研究时所用试验设备,结合现有研究成果,提出了关于含裂隙类岩石力学试验研究的发展趋势。结果表明:裂隙的数目、倾角及形状均会对含裂隙类岩石试件的力学性质产生显著影响。
Due to the uneven texture of the natural rock,it is hard to ensure the same properties of each sample,thus a rock-like material was used as replace,and the research progress on it in recent years was elaborated,including the mechanical characteristics of fractured rock-like material under dif-ferent fracture numbers,the different fracture inclination angles and the different fracture shapes.Through deep analysis of prefabricated fractured rock-like material specimens,the mechanical characteristics of fractured rock-like material specimens in the single axial compression test,the biaxial compression test,the triaxial compression test and the numerical simulation test were conducted and studied.The influencing factors of different fracture numbers,inclination angles and shape of fractured rock-like material specimens were discussed.The results show that the number,inclination angle and shape of fractures have played significant impacts on their mechanical characteristics.In addition,various equipment for fractured rock-like material research and testing was introduced,and the future development trend of fractured rock-like material tests was proposed.
