| 摘 要： | 结合对西南山区高速公路的109个边坡实例统计分析,得出层状边坡失稳与边坡岩性,岩层的倾角、厚度及边坡坡脚和坡高的关系。分析岩层倾角的大小与边坡失稳的关系,得出岩层倾角大小与边坡失稳的关系,运用极限平衡等理论,推导不同岩性边坡失稳的极限高度计算公式,通过实例证明了公式的可靠性。

| Abstract: | Considering statistical analysis about 109slope example of expressway at southwest mountainous area in china,the paper obtained the relation between the failure of the layered slope and lithology character of the slope,the rock layer inclination angle,thickness,the slope toe and the slope height.It also analyzed the relation between rock layer inclination angle and the failure of the layered slope and obtained the relation.Using limiting equilibrium theory and so on,the paper derivate ultimate altitude formula of the failure of different lithology,and the formula were proved by examples. |
