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 ,并以最小干扰能量曲面作为潜在滑动边界 Based on the energy criterion and slope structure analysis, the method of determining the slip direction and the most unfavorable sliding surface of layered rock slope is described. Based on the analysis of layered rock slope structure, a semi-quantitative method to determine the slip direction is proposed and the most unfavorable interference displacement is determined. According to the most unfavorable interference displacement that has been determined, the interference energy value and interference energy isosurface at each point within the slope are calculated, and the minimum interference energy surface is used as the potential sliding boundary
