摘　　要：采用理论分析方法研究了焊接钢筋网受力和变形之间的关系,利用数值模拟方法分析了不同支护形式下钢筋网的承载和变形特征。给定25kN载荷,得到了不同边界约束条件下钢筋网的最大变形值,以期为锚杆支护金属网的选择和施工提供依据。Theoretical method was applied to obtaining the relationship between force and deformation of welding steel fabric and numerical simulation was used to analyze load bearing and deformation characteristic of steel fabric under different supporting types.Given 25kN load,maximum deformation value of steel fabric was obtained under different boundary conditions.Results might provide reference for selection of steel fabric in design of anchored bolt.
