摘要:
依托山西省浑源县某花岗岩露天矿,经过现场地质调查和室内物理实验,得到该矿区边坡的结构面参数和岩体力学参数。利用极限平衡法结合slide软件对矿区在施工过程中可能会形成边坡失稳的情况进行计算,分析坡体破碎带和潜在滑体厚度对边坡稳定性的影响,锁定边坡潜在滑动面,计算出安全系数。结果表明,矿区西边坡开采至最终高程时,边坡不稳定,易发生滑坡。得到边坡的安全系数随滑体厚度的增加而变小,但在滑体厚度为20 m开始幅度趋于平缓,潜在滑移区位于边坡坡面以内25 m附近,同时发现破碎带的位置分布对边坡的稳定性起着决定性的作用。
Abstract:
Taking a granite open-pit mine in Hunyuan County of Shanxi Province as engineering background, based on site investigation results and indoor physics experiments, the structural surface parameters and rock mechanical parameters of the slope are obtained. The limit equilibrium method combined with the slide software is used to calculate the slope instability during the construction of the mining area, analyze the influence of slope fracture zone and potential sliding body thickness on slope stability, and lock the potential sliding surface of the slope to calculate the safety factor. The results show that when the west slope of the mining area is mined to the final elevation, the slope is unstable and landslides are prone to occur; the safety factor of the slope is smaller with the increase of the thickness of the sliding body, but the amplitude of the sliding body tends to be gentle at the thickness of 20m, and the potential slip region is located within 25m of the slope. Besides, the distribution of the fracture zone plays a decisive role in the stability of slope.
