摘　　要：排土场边坡属人工堆砌高大边坡,对其稳定性进行设计和计算是在露天煤矿日常生产中不可回避的重大工程问题。基于极限平衡理论的各种边坡稳定分析方法在工程实际中得到了极其广泛和有效的运用,以神华北电一号露天煤矿为例,经过FLAC/SLOPE多次分析和验算表明,SL露天煤矿排土场的设计参数符合矿山安全生产条件,在技术上是合理的、安全的、可行的,并给出了排土场边坡治理建议。The slope of the dumping site is an artificial made high slope.The design and calculation of the stability to be conducted would be an unavoidable important engineering issue in the daily production of the surface mine.Base on the limit balance theory,different slope stability analysis methods were widely and effectively applied to the engineering practices.Taking Shenhua Beidian No.1 Surface Mine as an example,several analysis and calculations with FLAC/ SLOPE showed that the design parameters of the dumping site of the No.1 Surface Mine could meet the mine safety production conditions and could be rational,safety and feasible in technology.The paper provided the proposals on the slope control of the dumping site.
