| 摘 要： | 本文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，将其解析解和数值模拟结果进行比较后发现：正弦模型求得的渗透系数要比锯齿模型大，其几何水力学效应显著，现已将其运用于实际工程。

| Abstract: | Based on the hydraulical and geomechanical characteristics of the irregular fractures,the sinusoidal flow model and the sawtooth flow model under laminar flow condition are put forward. It is shown that the permeability evaluated by sinusoidal model is higher than by sawtooth model by comparing the analytical result with the numerical result,and the geometric hydraulical effects are obvious. An example applied to a practical engineering is given. |
