大悬臂宽梁独塔斜拉桥的总体设计与创新

Overall Design and Innovation of Long-cantilever Wide-girder Single-pylon Cable-stayed Bridge

随着我国美丽城市的建设发展,市政桥梁的景观要求愈发重要。以金华金婺大桥重建工程为背景,从结构合理的角度分析结构布置与桥梁景观的相互影响,形成结构合理的、景观性较好的景观独塔斜拉桥。同时对大悬臂横梁体系的悬臂构造设计创新,可为类似桥梁提供一定的经验参考。

With the construction development of beautiful city in China, the landscape requirements of municipal bridge are more and more important. Taking Jinhua Jinwu Bridge Reconstruction Project as the background, this paper analyzes the interaction between the structure layout and the bridge landscape from the viewpoint of rational construction to form the landscape single-pylon cable-stayed bridge with the reasonable structure and good landscape. At the same time, this paper introduces the innovation of cantilever construction design of long-cantilever crossgirder system, which can be referred for the future similar bridges.
