【摘要】：为提高复杂地质条件下高陡边坡建模、稳定性评价与优化设计的准确性和效率,依托城门山铜矿高陡边坡,提出了一套融合地形信息、地质信息与力学信息的集成技术。充分利用已有地质数据,应用Dimine数字采矿软件系统平台,提出基于勘探线地质剖面建立高陡边坡三维地质模型的方法,实现复杂岩体的三维可视化。对三维地质模型进行剖切运算获得计算剖面,转换为AutoCAD绘图交换文件,导入Slide边坡稳定分析软件,实现数据文件在地质建模和力学分析软件之间的无缝传递。自动搜索求解计算模型的最小安全系数和临界滑动面,实现复杂地质条件下高陡边坡稳定性评价。最后,提出了一种基于二分法的边坡结构参数严格优化方法。
[Abstract]:In order to improve the accuracy and efficiency of high and steep slope modeling, stability evaluation and optimization design under complex geological conditions, a set of integrated topographic information was proposed based on the high and steep slope of Chengmenshan Copper Mine. The integration technology of geological information and mechanical information. Based on the Dimine digital mining software system platform, the method of establishing 3D geological model of high steep slope based on geological profile of exploration line is put forward by making full use of existing geological data. The 3D visualization of complex rock mass is realized. The calculation section is obtained by cutting the 3D geological model, and the AutoCAD drawing exchange file is converted into the Slide slope stability analysis software. To realize the seamless transfer of data files between geological modeling and mechanical analysis software, to automatically search and solve the minimum safety factor and critical sliding surface of the calculation model, and to realize the evaluation of the stability of high and steep slopes under complex geological conditions. A strict optimization method for slope structural parameters based on dichotomy is proposed.
