摘　　要：针对不规则裂隙的水力学特性和结构面地质力学特征，提出了层流状态下的正弦渗流模型和锯齿渗流模型，将其解析解进行比较发现，正弦模型求得的渗透系数要比锯齿模型求得的大，其几何水力学效应显著，并将其应用于实际工程．In this paper, the sinusoidal flow model and the sawtooth flow model are prospected at the laminar flow based on the hydraulical and geomechanical characteristics of the irregular fractures, and it is shown that the permeability evaluated by sinusoidal model is higher than that evaluated by sawtooth model by comparing their analytical results. The geometric hydraulical effectS are much more obvious, and an example applied to practical engineering is given.
