摘　　要：刚构—连续组合梁桥需经历墩梁临时固结拆除的体系转换过程,该种桥型属于超静定体系,临时固结的拆除会对桥梁结构成桥后位移和应力产生影响。探索该桥临时固结的拆除顺序对结构的影响,以达到优化合龙方案的目的,为今后该类桥梁的临时固结拆除方案提供相应的参考。Rigid Frame-continuous composite girder bridge requirement a process that temporary consolidation of the pier beam removal of system transformation,this bridge belong to a statically indeterminate system,the removal of temporary consolidation will impact for the bridged＇s displacement and stress of bridge structure.Explore the impact of the bridge＇s temporary removal of the consolidation order on the structure,in order to achieve the purpose of optimizing the closure program,and to provide the appropriate reference for the temporary consolidation of such bridges in the future dismantling program.
