某客专特大桥钢混结合梁翼缘板现浇角钢支架检算

Check Computation of Big Bridge Steel and Concrete Bond Beam Flange Plate Cast-in-situ Angle Steel Support of A Passenger Line

在桥梁跨越地物的施工条件受到严格限制或者桥梁跨度为非标准跨度时,采用简支钢混结合梁进行调跨。对某客专特大桥钢混结合梁上翼缘板现浇角钢支架进行强度、刚度及稳定性检算的结果显示,角钢支架力学性能符合规范要求。为今后类似条件的施工临时结构检算提供参考。

When the construction condition of bridge across the terrain is restricted or bridge span is non-standard, the simply supported steel and concrete bond beam is used to adjust span. The check computation of strength, rigidity, and stability of a big bridge steel and concrete bond beam flange plate cast-in-situ shows that the mechanical properties of angle bracket conforms to the standard, providing reference for check computation of temporary construction under similar conditions in future.
