摘要
从能量准则和边坡结构分析出发 ,阐述了层状岩质边坡滑向和最不利滑面的确定方法。文中以层状岩质边坡结构分析为基础 ,提出了确定滑向的半定量方法 ,并进一步确定出最不利干扰位移。根据已确定的最不利干扰位移求得边坡内各点的干扰能量值及干扰能量等值面 。
Based on the energy criterion and analysis of the slope structure, the methods are discribed to determine the slide direction and the most disadvantageous slide surface of the layered rock slope. The semi guatitative method is suggested to determine the slide direction on the base of analysis of the layered rock slope structure, and the most disadvantageous interference displacement is determined. According to the determined interference displacement, the value of the interference energy of each point in the slope and the equivalent surface of interference energy are determined. Then, the curved surface with the minimum interference energy is taken as potential slide boundary.
