Abstract
The highway project in the loess area of northern Shaanxi is to balance the earthwork and save costs, and a large number of excavation slopes are set. In the loess area, the soil is soft. If there is a structural surface, it is easy to cause damage to the airspace, causing huge losses to highway construction and transportation on the heavy rain and other working conditions, especially the roadside slope. Taking the high loess slope of a section of Zhidan-Nanliang Red Tourism Highway as an example, the indoor parameters are used to determine the appropriate parameters. The Midas-GTS NX strength reduction method is used to analyze the slope stability under different slope cutting rates.
