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。
Udec software was used to analyze the 301m high slope in North Fujiwu Mine open pit in 4 steps. The measured and calculated slope displacement, actual and calculated characteristics of slope deformation and failure were analyzed in detail It is concluded that the slope failure mode is dumping-sliding landslide. A main conclusion is that the udec model analysis software is a powerful tool for studying the failure mechanism of slopes and making landslide forecasts in a timely manner.
