    新型锚管构架在边坡加固中的应用

    APPLICATION OF FRAMEWORK OF CABLE AND TUBE REINFORECEMENT TO SLOPE STABILIZATION

    • 摘要: 针对边坡病害治理工程往往存在工期紧、施工场地受限等特点,研究了一种用于边坡加固的新型结构,即锚管构架。介绍了锚管构架的组成和特点,基于Winkler理论,建立了锚管构架的力学计算模型,并编制了弹性杆系有限元计算程序。将锚管构架应用于西气东输管道沿线某填土边坡的病害治理中,结果表明,按照Winkler理论建立的计算模型较好的反映了锚管构架实际的受力和变形形态,输气管道的安全运营得到了保障。

       

      Abstract: 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.
