摘　　要：排土场下游常分布有居民区、厂房等设施,一旦滑坡,后果严重。为了准确预测排土场滑坡的影响程度及影响范围,通过分析排土场滑坡风险源项,采用规范确定法、能量方程法、工程类比法及传播公式法对某排土场滑坡后的影响范围进行了计算,得出了某排土场滑坡后的最大影响范围长度为208 m,并进行了影响程度分析,对于排土场的防治及监管具有一定的指导作用。Residential areas,factories and other facilities are often distributed downstream of the dump site.Once the landslide occurs,the consequences will be serious.In order to accurately predict the extent and scope of impact of the dump landslide,by analyzing the risk source terms of the dump landslide,the norm determination method,energy equation method,engineering analogy method and propagation formula method are used to affect the impact range of a dump yard after a landslide After calculation,it is concluded that the length of the maximum impact area after a landslide of a dump is 208 m,and the impact degree analysis is carried out,which has a certain guiding effect on the prevention and supervision of the dump.
