摘　　要：既有公路桥连续梁上跨高速铁路,对该连续梁的拆除施工方案进行分析。分别针对边跨切割履带吊整体拆除、整体顶推、跨中切割后顶推拆除三个施工方案进行研究。分析各方案中连续梁的加固措施、内力、施工风险等因素,为该工程的安全实施提供优化建议。The existing continuous beam crosses high-speed railways.Analyzing the demolition construction plans for continuous beams.Studying the following three construction plans.The first scheme is to cut the beam at the edge span and then use a crawler crane to remove the mid span beam.The second scheme is to directly move the entire beam.The third scheme is to cut the beam at the mid span and then push the beam forward.Analyzing the reinforcement measures,internal forces,construction risks,and other factors of continuous beams in each scheme.Providing optimization suggestions for the safe implementation of the project.
