某宽幅连续刚构桥挂篮主桁架优化设计

Optimization design of hanging basket main truss of a wide continuous rigid frame bridge

以某宽幅连续刚构桥工程为依托,对该桥悬浇施工挂篮进行主桁架的优化设计,以挂篮中与前横梁相联的主桁架上部拉杆与水平面的夹角作为控制参数,通过对比不同控制参数下挂篮构件的强度和刚度分析,以达到选取优型挂篮主桁架形式的目的。

In a wide range of continuous rigid frame bridge project, the bridge cantilever hanging basket construction optimization design for the main truss, the main truss rod angle and the horizontal plane to the hanging basket in the front beam and connected as control parameters, through the analysis and comparison of different stiffness control parameters of cradle member strength, in order to achieve selection good type hanging basket to form the main truss.
