摘　　要：我国目前对于水在混凝土裂缝中的研究还没有统一的标准，所采用的也大多是岩石水力学中的岩体裂隙渗流理论，由于混凝土裂缝和岩石裂缝存在很大的差别，所以对其研究和应都造成了很大的困难。本文详细介绍了基本的平行板渗流理论及其采用凸起高度、隙宽函数、节理粗糙度JRC、面积接触率四种形式的修正立方定理。探讨了各种方法的优缺点，及对其在混凝土裂缝中的应用进行了一定的说明，对今后该方面的研究有一定的借鉴作用。There is no uniform standard to study the Seepage in fractured concrete, the theory of Seepage in fractured rock in rock hydraulicsis widely used in this field, but there is a big difference between the concrete cracks and ,fracture of rock, resulting in difficulties of its research and application in the field. This paper introduces the basic parallel plate percolation theory in detail, and four forms of modified cubic law, using height of projection, gap width function, joints roughness JRC, area contact rate. The advantages and disadvantages of every method are discussed, and the application of four methods in fractured concrete is illustrated, providing a certain reference in future researches in this field.
