岩体结构面网络计算机模拟分析是近代计算机技术在岩石力学领域应用的一个重要方面．在工程实际中，岩体结构面的分布情况是极为复杂的．但从统计意义上讲，反映岩体结构面分布特征的几何参数则是服从一定的统计规律的．因此可以通过现场实地调查和室内统计分析，建立结构面几何参数的概率统计模型，进而应用蒙特卡洛随机模拟原理和方法，在计算机上求得表征结构面分布特征的节理网络图像．应用这一方法的有关成果已在李家峡、龙滩、小湾、三峡等工程中获得了大规模的应用．
Computer simulation of rock mass structural plane network is an important aspect of the application of modern computer technology in rock mechanics. In engineering practice, the distribution of rock mass surface is extremely complicated. However, from a statistical point of view, the geometric parameters that reflect the distribution of structural planes of rock mass are subject to certain statistical laws. Therefore, through the field investigation and indoor statistical analysis, the probability statistical model of geometric parameters of structural plane can be established. Then the Monte Carlo stochastic simulation principle and method can be used to obtain the joint network image which characterizes the distribution of structural plane. Relevant achievements of this method have been applied in large scale in such projects as Lijiaxia, Longtan, Xiaowan and Three Gorges.
