摘要
格宾挡墙作为一种新型的支挡结构,虽然可采用传统力学方法进行设计,但无法掌握其变形特性.为了确切地掌握格宾挡墙结构的应力变形特性,通过对多组格宾单体结构进行压缩和直剪试验,推算出格宾单元的黏聚力c和内摩擦角φ,并据此以案例形式采用有限元的方法分析了格宾挡墙的应力变形特性,为工程设计提供理论参考.
As a new type of retaining structure, gabion revetment can be designed by the conventional mechanical calculation and stability analysis. However, the commonly used conventional method is difficult to analyze the deformation characteristics of loaded gabion structure. To approach the deformation behavior of gabion structure exactly, based on compression and direct shear tests of monomer groups of gabion structure, the cohesive force and internal friction angle of the sample gabion retaining wall are deduced. According to the case, stress and deformation properties of the gabion retaining wall are analyzed by using finite element method. This can provide a theoretical basis for engineering design.
