| 摘 要： | 强震产生的地震波会对路基边坡造成巨大的破坏,严重摧毁道路、阻碍救援。基于这种具有强大破坏性的自然灾害,建立"地震波效应—地震力作用于边坡体—演化极限"形成的波动袭击链,根据地震波效应和地震力作用分析地震波致灾机理和路基边坡严重破坏的地质灾害形成机理,最终得出路基边坡发生破坏的演化极限,给出演化极限的判剧条件,运用于工程实例。

| Abstract: | The strong earthquake waves cause great destruction to embankment slope,seriously destroyed roads and hampered the aid.Based on the strong destructive natural disaster,the writer put forward the secondary disasters chain ＂collapse-slide mud-weir-water＂,and put forward the reflected wave model of seismic and safety coefficient equation of embankment slope.It reveals the destruction mechanism of strong earthquake cause embankment slope destroy.finally,this paper reveals evolve limit and distinguish conditions. |
