摘　　要：采用ｕｄｅｃ软件对富家坞露天矿北帮３０１ｍ高边坡分４步开挖作数值分析，对实测与计算的边坡点综合位移矢、实际与计算的边坡变形破坏特征均作了详细对比分析，得出边坡破坏模式为倾倒滑移式滑坡。一个主要结论为：ｕｄｅｃ模型分析软件对研究边坡破坏机制并及时作出滑坡预报都是十分有力的工具。In this paper UDEC software is used to analyse the values of 4 step excavation of the 301-m slope of north wall, Fujiawu Open pit. A detailed comparision is made between the actual and calculated values of its combined displacement vectors and slope deformation failure characters. It is concluded that its slope failure is the toppling sliding type and the UDEC analysing model softwares are the powerful tool for investigating the slope failure mechanism and predicting the slope sliding.
