摘　　要：岩石单裂隙渗流特性是研究裂隙岩体渗流的基础,由于岩体工程实践的迫切需要,国内外研究者众多.本文以岩石单裂隙渗流的数值模拟和实验室试验的研究内容为线索,综述了粗糙度、隙宽、曲折流、沟槽流、平行板模型等概念和应力、温度、各向异性、入渗水头、尺寸效应、溶解等因素对岩石单裂隙渗流的影响,最后给出了目前存在问题及展望.Flow properties through a single rock fracture are the foundation of fluid flow research in fractured rock masses. Many researchers at home and abroad are engaging in the subject for the urgent need of engineering practice. Based on clues of numerical simulation of a single rock fracture and laboratory tests, the concepts of roughness, aperture, tortuosity and channeling flow are introduced, and influencing factors of stress, temperature, anisotropic, inlet head, scale effect, solution, etc are elaborated. Finally, some research work should be done in future are given.
