“…Based on a reasonable constitutive model and the finite element or finite difference method, the numerical calculation model of slope under arbitrary conditions can be constructed quickly to calculate the deformation of slope under different working conditions. Based on the traditional finite element/finite difference theory, the strength reduction theory of finite element/finite difference is a new method used to simulate the process of slope deformation and instability by reducing the strength parameters of rock and soil mass to obtain the safety factor of a slope [25][26][27][28]. By using the finite element/finite difference strength reduction method, combined with relevant mathematical methods and image processing technology [29,30], the process of slope deformation and instability can be visually displayed, and the mechanism of slope instability can be explained well.…”

Using prestressed anchor cables is one of the most common approaches for reinforcing slopes. By establishing a calculation model for a high and steep slope, the changes of displacement of slope foot and increment of force on the cables under different prestresses were calculated. Furthermore, the influence of prestress on the changes of displacement of slope foot and force on the cables was analysed. By analysing the changes in force on cables in different parts of the slope, the reinforcement mechanism of a prestressed anchor cable on the slope was attained. The result showed that the reinforcement effect of prestressed anchor cable on the slope was mainly attributed to it effectively restricting the displacement of sliding mass in the slope, while the effect of cables in the lower part of the slope was more significant than that of those in the upper part of the slope. Therefore, to reduce the number of cables, decrease the construction difficulty of cables and save money, it is feasible to remove cables in the range of the upper-third of the slope. Afterwards, by improving the cable prestress in the range of the lower-third and reducing the cable prestress in the middle, the safety factor of the slope can satisfy design requirements, thus reinforcing the slope.

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.
