Dynamic Analysis Of Slope Anchored By Self-adapted Anchor Cables

China is a country where are earthquake disaster occurs frequently,especially in west-south area.The earthquake of slope brings serious threat to peoples' life and treasure.The dynamic stability of slope is being taken more and more attention around all the engineering construction.The prestressed anchor cable is a type of rod component which is main bear tension.The function of prestressed anchor cable is through stranded wires which are anchored in the deep stable rock stratum tensioning at the surface of rock to improve the strength and stability of soil mass.Therefore,the research on dynamic stability of prestressed anchor cable in slope is a significant issue.The paper combines the new self-adapted anchor cable and finite difference method soft FLAC3 D 5.01 to numerical modeling and study the dynamic stability of slope reinforced by self-adapted anchor cable under earthquake load.The specific research details are as follow:Firstly,the paper introduces the stability of slope according to former research.Types of destruction of slope are classified.Then the computational formula of anchor force of slope and anchorage length is listed according to the code,laying a solid foundation for later numerical simulation.Secondly,the new self-adapted anchor cable is introduced.The paper makes simplification and improvements in numerical simulation aim at mechanism of self-adapted anchor cable,which add a spring unit to replaces the sliding sleeve,meaning to show the active deformation and anti-seismic property.Then,the paper combines a foundation ditch slope in south-west area to analyze stability under nature condition,calculating the anchor force according to the project and showing the parameter of anchor cable.The result reveals that prestressed anchor cables improve the stability of slope.Finally,combining the theory of dynamics and the former engineering,the paper analyzes dynamic stability of slope reinforced by self-adapted anchor cables under different earthquake load.By changeling the peak acceleration of seismic wave,the influence to self-adapted anchor cable is different but disciplinarian is almost the same.The paper has verified the superiority of self-adapted anchor cable in aspects of max displacement of slope?magnification coefficient of the acceleration?cable axial force and cable deformation.The result provides thought and direction of design new seismic anchor cable,which is of importance and practical significance.
