摘　　要：新建高铁与既有运营线并行地段,造成既有公路改道,加之既有上跨铁路的公路桥梁受孔跨长度、平面线位、荷载等级等约束,从而上跨既有运营线公路桥需要拆除、重建。本文介绍了采用双导梁架桥机拆除上跨营业线桥梁施工技术措施,为今后拆除类似桥梁提供了有益借鉴。The newly-built high-speed railway and the existing operation line are parallel to each other,resulting in the diversion of the existing highway.In addition,the existing highway bridge crossing the railway is constrained by the span length,plane line position and load grade,so the highway bridge crossing the existing operation line needs to be demolished and rebuilt.This paper introduces the construction technical measures of using double guide beam bridge erecting machine to demolish the bridge across the business line,which provides a useful reference for the future demolition of similar bridges.
