摘要
结合白云鄂博铁矿东矿C区出现的边坡失稳问题,选取具有代表性的剖面,采用离散元软件UDEC对该边坡当前状态、按原计划开挖状态进行模拟计算及稳定性分析和评价,并且对模拟的结果进行了对比分析。同时根据现场情况及模拟结果,对C区边坡失稳提出卸载及加固方案。
In combination with the slope instability in Section C of Baiyunebo Iron Mine,the simulation calculation and the stability analysis and evaluation are made for the present state and the future state when the excavation is completed according to the original plan by selecting representative sections and using discrete element software UDEC.The simulation results are compared and analyzed.The unloading and consolidation scheme for the instable slope in Section C is proposed based on the site condition and simulation results.
