摘　　要：为使珲春曙光金铜矿外排土场在保证边坡稳定的前提下最大限度增容,通过现场勘查、室内试验、反分析等手段确定排土场岩土体参数。利用极限平衡方法对排土场稳定性进行评价,提出增容方案及排土场稳定性防治措施。In order to increase the expansion of Hunchun Shuguang gold and copper mine under the premise of guaranteeing the slope stability, this article determines the parameters of rock and soil mass through on-site investigation, indoor test and methods of back analysis. Based on the limit equilibrium method, this article evaluates the slope stability and proposes the expansion plans and prevention measures of dump stability.

关 键 词：室内试验 稳定性 增容 防治措施
