摘要
上海市昆阳路越江工程采用独塔斜拉桥形式跨越黄浦江,江中心设塔。涉水施工的不确定性以及与河道通航的相互影响增加了索塔建造的难度,施工控制尤为重要。现依托昆阳路大桥水中索塔建造,结合黄浦江的航道特点和建设环境,分析大型斜拉桥位于内河航道中心的索塔建造关键控制技术,可为今后类似工程提供一定的借鉴。
A single-tower cable-stayed bridge is built across the Huangpu River,linking Kunyang Road and Puwei Highway in Shanghai.The bridge tower is situated in the middle of the river.Due to the uncertainties of construction in water and the mutual influence between the construction and the adjacent waterway navigation,the difficulty of building bridge tower is increased.Therefore,the construction control plays a significant role.Aiming at the characteristics of the waterway and the construction conditions in the Huangpu River,this paper takes the Kunyang Road Bridge tower as an example and discusses the key technologies of its construction control.Favorable engineering benefits are obtained,which can provide some valuable reference to similar projects.
