One of distinct characters of geotechnical problems is that there exist various interfaces such as interface between the structure and geotechncal medi8 , the joints in rock mass , sliding face in soi1 and so on , which will effect the mecbocal behaviors of the geotecndcal media and the structures significanly so far though the finite element method has been wildly used in geotecbocal field , it still remains an inthectable problem to simulate these inteffoces idealiy in the numerical analysis 计算对象的不连续性是岩土工程问题的一个重要特点，这些不连续面主要是存在于基础?土体、挡土结构?土体、地下结构?围岩等结构与周围岩土介质问的界面，或是岩体中的节理或软弱夹层、土(岩)滑坡的滑动面等。不连续面的存在显然对结构及岩土体的受力变形有着不可忽略的影响，因此在计算中不应无视它的存在。
An significant symbol has been used to determine the technique of 3 - d discontinuities network modeling of rock mass is good or not , which is to check whether the model can reappear the reality situation of rock mass or not , in order to make the 3 - d network model to meet the need of the actual rock engineering , the methods to verify the result of the modeling are required , one of the method to be used is to compare the figures between the section of the numerical model and the sampling window of in - situ model , the second method to be used is verify the data set between the numerical model and field data , only if the verification obtained a good precision , then the model can be considered as a efficiency model , and it can be applied into the actual rock engineering 摘要岩体随机不连续面三维网络模拟技术成熟与否的一个重要标志就是最终的网络模型是否能够较真实地再现岩体的实际情况，为了使三维网络模型的结果能够真正地应用于实际工程，就必须对模拟的结果进行必要的检验，检验的办法就是将模拟出的模型剖面图形与原型测量窗口的图形进行图形对比，或者将原型的观测数据与模型的测试数据进行数据对比，当这种检验达到精度时，模拟出的模型为有效模型，可以投入工程实际应用。
