Simulation of 5-m Graded Loess Slope Stability in South-Central Ningxia
According to the information on constructed highways in loess areas in Ningxia,the cutting slope of loess highways in south-central Ningxia was simulated and calculated by the finite element method.Focusing on a single-grade 5-m natural slope,this paper studied the effects of various factors including slope rate,platform width,and intermediate wide platform on safety factors of the slope.Combined with the specification,land occupation,earth,and other comprehensive factors,the recommended cutting slope form under different excavation depths below 20 m was put forward,which could provide a reference for the cutting slope design for loess highways in Ningxia in the future.
