摘　　要：为合理评价三峡库区高阳段库岸岩体结构特征,为工程整治提供依据,对区内岩体进行了裂隙调查及网络模拟研究。通过野外岩体裂隙的实际测量和调查,建立了较为符合实际的结构面几何参数概率模型。应用蒙特-卡洛法和直接法原理,利用计算机模拟得出符合实际的二维裂隙网络图,并进行了一些改进和有关问题的探讨,如广义RQDt计算、裂隙线连通率计算等。最后在此基础上对研究区内岩体的工程地质性质作出切实的评价。In order to rationally evaluate structural characteristic of the rock masses in Gaoyang section of Three Gorges Reservoir and provide guidance for engineering disaster harnessing, the fracture investigation of rock masses was carried out and joints network was simulated. By the field survey of discontinuous of rock mass, a probability model of the geometic parameters of discontinuous, which is accord with the actual situation, was established. The two dimensional joints network was simulated by means of computer simulating technique base on monte - carlo method and direct method, in which some technical improvement was proposed such as calculations of generalized RQDt and line connection rate, based on this the evaluation of geologic engineering characters of rock mass was made more accordant with the real condition.
