Research on Numerical Simulation Analysis and Engineering Application of Prestressed Anchor Cable Construction

Abstract

AbstractThe prestressed anchor cable can improve the overall stability of the rock and soil mass of the slope, thereby improving the mechanical properties of the rock and soil mass, and can better control the structural displacement, and achieve the purpose of reducing landslides, dangerous rocks and dangerous rocks. At the same time, the pre-stressed anchor cable construction is convenient, fast in progress, and economical, and has a broad application space. Based on the actual engineering background, this paper analyzes the key technologies in the construction process, and uses finite element software to conduct an overall numerical analysis of the soil after the use of prestressed anchor cables. It analyzes the impact of different slope top loads and finds that for non-prestressed anchor rods, the depth of action is limited, excessively increasing their length will not only cause difficulties in construction, but also have no practical significance. When prestress is applied, the horizontal displacement of the baffle is not uniform under the action of different prestress and slope top load, showing a twisting phenomenon. Along with the increase of the slope top load, the lateral pressure also increases, which causes the displacement of the baffle to decrease with the increase of the slope top load. The research in this paper will have certain guiding significance for the engineering application of prestressed anchor cables.
