公路与桥梁过渡段施工技术探讨

Discussion on the Construction Technology of Transition Section Between Highway and Bridge

总结了公路与桥梁过渡段常见的施工问题,包括桥头路基失稳、路堤防护力度不足、桥台台背填土压实度不足,从施工前准备、施工组织设计方案编制、基层处理、路堤作业、路基作业、台背作业等方面研究了道路桥梁施工中过渡段的施工技术要点,以确保公路与桥梁过渡的平稳性以及车辆在过渡段通行的顺畅性与稳定性,减少过渡段施工对公路与桥梁连接处平整度的影响,提高过渡段的施工质量。

The common construction problems of highway and bridge transition section are summarized,including unstable subgrade of bridge head,insufficient protection of embankment,insufficient compaction degree of backfill of abutment.The key technical points of transition section construction in road and bridge construction are studied from the aspects of pre-construction preparation,construction organization design scheme preparation,basic treatment,embankment operation,subgrade operation,platform back operation,etc.,so as to ensure the smooth transition ofhighway and bridge and the smoothness and stability of vehicles in the transition section,reduce the influence of the construction of the transition section on the smoothness of the junction of highway and bridge,improve the construction quality of the transitionsection.
