| 摘 要： | 边坡失稳并不一定是连续性破坏,而可能存在先在一局部处达到极限状态,然后向其它部位扩展的渐进失稳破坏。运用概率分析的方法求解局部失稳概率,论证了渐进失稳概率分析的可能性,最后提出了治理边坡渐进失稳的措施。

| Abstract: | Slope stability failure is not definitely serial but probably gradual.First,it reaches the extreme state at certain part of slope and then extends to the other parts.Probability method was used to solve partial failure probability,which verifies the feasibility of gradual failure probability analysis.At last,some measures to deal with gradual slope stability failure were proposed. |
