Simulation And Effect Evaluation Of Anchor Cable Support For Wumupu High Slope Of Biwei Expressway

In recent years,with the persistent economic growth and the further implementation of development policy,highway traffic construction increased continuously.At the same time,the problem of highway slope safety is critical.Slope instability caused by the disaster has been increased year by year,and made a great deal of injuries and loses in life and loses in wealth.The traditional supporting structures such as gravity retaining wall,counterweight retaining wall,cantilever retaining wall,and buttressed retaining wall exposed faced problems in engineering application,therefore remedy and treatment of highway slope has become even more important than before.Recently anchor cables,as a new flexible support structure,that are widely applied in many highways slope support.Comparing with the traditional slope retaining structure and anchor cables showed advantages being lightweight economical and stable for long term use.Using the finite difference method,the numerical simulation can be effectively used to evaluate effectiveness of a support scheme.In present study explore the anchoring effect and coordinated working performance of adaptive anchor cables in the reinforced Wumupu high slope a numerical simulation model is established by FLAC^3D.The study contents are as follows:（1）The basic features and the computable principles,the building of the model and the choice of the structure element of the FLAC^3D will be introduced,meanwhile simulation is done to prove the feasibility of the support structure.（2）Analysis of the plastic zone and the comparison between safety factor between unreinforced and reinforced slopes is performed.（3）Displacement analysis including vertical and horizontal displacement of slope before and after reinforcement is evaluated.（4）Field monitoring data is analyzed to evaluate the change in displacement during the process of excavation and after the reinforcement.
