以4跨独柱曲线梁桥为例,采用空间有限元程序进行建模计算分析,验证桥梁在各种静力荷载和移动荷载偏载作用下的整体稳定性,确定桥梁存在整体倾覆破坏安全隐患时的边界条件,并提出加固维修方法,为类似曲线梁桥的加固维修提供一定参考。
Taking the 4-span single-column curve girder bridge as an example, the finite element program of the space was used to conduct the modeling calculation and analysis to verify the overall stability of the bridge under all kinds of static loads and moving partial loads. It was determined that the overall overturning failure of the bridge posed a potential safety hazard The boundary condition is proposed and the method of reinforcement and repair is proposed to provide some reference for the reinforcement and repair of similar curved girder bridges.
