| 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: | An integrated methodology combating topographic information,geological information and mechanical information was presented to improve the accuracy and efficiency of high and steep slope modeling,stability evaluation and optimization design under complex geological environment.Thc high and steep slope in the Chengmenshan Copper Mine was used as a case study.The available geological data was efficiently used.According to the geological profiles of prospecting lines,a methodology for 3D geological modeling was presented by using the Dimine software to realize 3D visualization of complex rock mass.The numerical profile was obtained by the cutting operation of 3D geological model,and then converted to a drawing exchange file.This file was imported to the Slide software to realize the seamless transmission of data files between geological modeling software and mechanical analysis software.The minimum factor of safety and associated critical failure surface of numerical model were automatically searched to realize high and steep slope stability evaluation under complex geological environment.Finally,a rigorous methodology for optimizing slope angle was proposed based on the bisection method. |
