岩体三维网络模拟技术及其在三峡工程中的应用

在对三维岩体开挖面上节理迹线生成及其迹线网络搜索技术进行深入研究的基础上，初步开发了相应的岩体三维网络模拟分析程序。程序分析内容包括：绘制任意给定开挖面或复杂开挖 的岩体节理迹线分布图；在三维迹线图上搜索出由结构面切割形成的各闭合块体区域，进一步搜索可称动性块体，并分析其几何特征值，如闭合块体区域面积及可移动块体体积等，根据对三峡工程船闸高边坡施工典型区段开挖面岩体结构的调查资料和分析结果，用已开

Research on 3 D Rock Joint Network Simulation Techniques and Its Application to TGP

Based on research works of generating 3 D joint traces on rock excavation surfaces and searching trace network technique, a corresponding computer program for 3 D joint simulation analysis was developed, which includes drawing 3 D rock joint trace distribution diagrams on any shaped rock excavation surfaces or complicated excavation borders, tracing all existing joint loops and all removable blocks formed by joint intersections and calculating their geometric feature values such as areas of joint loops and volumes of removable blocks. According to rock joint measurements in situ and their statistical analysis of typical area excavations during the lock's rock slope excavation process in the Three Gorges Project, the corresponding rock structure conditions have been simulated and analyzed by using this method and its computer program.
