APPLICATION OF FRAMEWORK OF CABLE AND TUBE REINFORECEMENT TO SLOPE STABILIZATION

This paper presents a new method to address some problems in slope hazard control projects just as urgent construction period, limited construction location and so on. The new method is a new style of reinforcement structure that is named framework of cable and tube reinforcement. The paper describes composition and feature of framework of cable and tube reinforcement, also analyzes the adaptability of it on the type of slope hazard. According to the computation principle and method of Winkler beam on elastic foundation, an analytic model of framework of cable and tube reinforcement is proposed. A computing program of elastic bar system FEM has been written. The structure is used to the treatment of a backfill slope hazard along west-east gas transmission pipeline. The results show that the model can agree well with practical stress and deformation of framework of cable and tube reinforcement. Certainly safe operation of gas transmission pipeline is ensured.
