摘要: 依托龙桥排土场工程,因排土场边坡堆排物中含水量较高,其无法堆积成高边坡排土场。针对稀湿废石土排土场边坡运用临界滑移场法搜索了边坡最危险滑面,提出了稀湿废石土的堆排方法,并结合Geo-Slope软件分析得出Ordinary、Janbu和Bishop 3种边坡稳定性评价下的安全系数。研究结果表明:采用钢筋石笼加固后的稀湿废石土边坡具有较高稳定性,解决了稀湿废石土安全堆排问题,为矿山安全开采提供了保障。Abstract: Relying on Longqiao dump project, due to the high water content in the dump slope, it can not accumulate into a high slope dump. The critical slip field method is used to search the most dangerous slip surface of the slope for the slope of the waste dump. The stacking method of the waste dump is proposed. Combined with the Geo-Slope software, the safety factors under the stability evaluation of Ordinary, Janbu and Bishop are obtained. The research results show that the slope reinforced by reinforced gabion has high stability, which solves the problem of safe stacking and discharging of the waste rock and provides guarantee for the safe mining of the mine.
