摘要

The purpose of this study is to evaluate hydraulic aperture in single fracture. First, four empirical models were compared with parameters of them. Then the results of numerical simulations by program, PHOENICS, in different aperture combinations and roughness conditions were discussed with the previous models. The results indicate that the ratio of the mean aperture to its standard deviation is an important factor of hydraulic aperture. So the relationship with the ratio and hydraulic aperture could be divided into three parts that the estimating empirical models is according to different roughness conditions.
