节理在岩体分布中具有随机性，为了讨论这种不确定性分布特征，建立了一个岩体节理网络的计算机模拟方法。该方法考虑了节理分布的不均匀性、方向性和成带性特点，采用非平稳态随机过程模拟节理间距，并通过Ｍｏｎｔｅ－Ｃａｒｌｏ方法产生仿真的节理网络，还给出了模拟实例。
The joint has randomness in the distribution of rock mass. To discuss the distribution of this uncertainty, a computer simulation method for the rock mass joint network is established. The method takes into account the heterogeneity, directionality and banding characteristics of the joint distribution. The non-stationary stochastic process is used to simulate the joint spacing and the simulation joint network is generated by the Monte-Carlo method. A simulation example is also given.
