Stability Analytical Method of Stepped Loess Cutting High Slope

Abstract:

stability analysis is the base for control the loess high slope in loess area. on the assumption of arc-model in below segment, straight slip surface in model, uprightness in the up sect, a general expression of safety factor for Step-shaped Cutting High Loess Slope is deduced According to the balance of force and torque balance. Regard the parameters of the intersection of arc and line coordinates of the location and the inclination of the line segment as variable, the loess high slope stability analysis are programmed, he automation of the calculation is achieved. This method is verified by k202+020～k202+158 loess high slipe in Huangling –YAN’AN expressway.
