| 摘 要： | 提出了一种更为简单的估算岩石断裂面粗糙度值的分形模型，可用来模拟岩石断裂面剖面线。断裂面愈粗糙，其分维值也愈大，并建立了分维值与ＪＲＣ值之间的经验方程。

| Abstract: | A simpler fractal model to estimate the joint roughness coefficient (JRC) is suggested.It can be applied to simulate rock discontinuity profiles.The rougher the surface,the greater the fractal dimension(D).An empirical equation between JRC and D was established.Using this equation,the JRC values of 6 joint profiles were estimated and they were very close to the typical JRC values. |
