摘要
桥梁作为连接城区路网的关键节点,深度影响城区整体交通运行,如何在桥梁群拆除重建时采取有效措施保障路网在施工期间的通畅性,需要利用科技手段对其保通方案进行设计与验证。以平陆运河钦州城区段跨线桥梁工程为例,利用宏观+微观交通仿真软件与BIM软件相结合的仿真分析方法,对跨线桥梁群集中改建施工期间保通方案的合理性进行综合评价。结果表明,该方法可为城区桥梁施工保通方案设计提供理论参考并验证其合理性,有效支撑运河沿线关键桥梁重建施工期间的交通管理,减小因桥梁拆建施工对交通流的影响。
Bridges are critical for urban road networks and greatly impact overall traffic operations.During the demolition and reconstruction of bridge clusters,it is essential to implement effective measures to ensure smooth traffic flow by designing and validating a scientifically sound traffic management plan.Taking the Pinglu Canal Qinzhou Urban Section Cross-line Bridge Project serves as an example,a simulation analysis method combining macro and micro traffic simulation software with BIM software is used to comprehensively evaluate the feasibility of the maintenance plan during the centralized reconstruction construction period of the overpass bridge group.The results indicate that the method successfully provides a theoretical reference and validates the rationality of the traffic management plan for urban bridge construction.It effectively supports traffic management during the reconstruction of vital canal bridges,minimizing the disruption caused by bridge demolition and construction on traffic flow.
