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

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