STUDY ON THE STABILITY OF MULTI-LEVEL SLOPES OF MIXED SOIL WITH DIFFERENT SLOPE TYPE COMBINATIONS
To reasonably excavate high slopes of mixed soil roadbeds in western Sichuan,this study investigates the stability of multi-level high slopes by considering three geometric parameters:platform width,slope ratio,and slope height.The results indicate that platform width,slope ratio,and slope height significantly impact the safety factor of slope stability.Specifically,the safety factor is positively linearly correlated with platform width,while it is negative-ly correlated with slope ratio and slope height.These findings provide valuable guidance for the design of multi-lev-el slopes in similar regions.
