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边界上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，进一步搜索可移动性块体，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。最后，根据对三峡工程船闸高边坡施工期典型区段开挖面岩体结构的调查资料和分析结果，用已开发的程序，对岩体结构条件进行了初步模拟分析。
Based on the deep research on the generation of the joint traces on the excavation surface of 3D rock mass and the search technology of the trace network, the corresponding program of three-dimensional network simulation analysis of the rock mass is preliminarily developed. The program analysis includes: plotting the joint distribution of rock mass joints on any given excavation face or complex excavation boundary; searching for the closed block region formed by structural face cutting on the three-dimensional trace map, and further searching Mobility block, and analyze its geometric characteristic value, such as closed block area area and movable block volume. Finally, based on the survey data and analysis results of the face rock mass structure in the typical section of the high slope of the Three Gorges Project during the construction period, the preliminarily developed procedures are used to carry out the preliminary simulation analysis of the rock mass structural conditions.
