摘　　要：随着福州西部片区的开发,既有洪塘大桥成为西向越江通道的瓶颈。对洪塘大桥进行拓宽改建以提高通行能力、打通交通瓶颈,早在10 a前就开始部署研究。工程研究设计阶段关于车道规模、老桥利用与否、立交改造与布设、特别是施工过程中的过江交通能否维持等总体方案进行决策,包括横向分幅分阶段拼装桥梁设计和全寿命周期桥梁设计,充分体现"以人为本、可持续发展"的城市更新理念。研究方法可为城市大型越江桥梁拓宽改建工程提供启发和借鉴。With the development of the western area of Fuzhou,the existing Hongtang Bridge has become the bottleneck of the westward tunnel across the river.In order to improve the traffic capacity&break through the traffic bottleneck,the research on widening&reconstruction of Hongtang Bridge started 10 years ago.This project studies the decision-making process of the overall scheme in the design stage,such as the scale of lanes,the utilization of old bridges,the reconstruction&layout of interchanges,especially whether the river crossing traffic can be maintained in the construction process,including the design of horizontally segmented,staged assembled bridges and the design of full life cycle bridges,all of which embody the urban renewal concept of people-oriented&sustainable development.These methods can provide inspiration&reference for urban large-scale river crossing bridge widening&reconstruction projects.
