上海城北预应力混凝土连续梁大桥工程的施工监控

On Construction Supervision & Control of Shanghai Chengbei Prestressed Concrete Continuous Girder Bridge

预应力混凝土连续梁桥的众多优点,使其广泛应用于城市桥梁、公路桥梁及铁路桥梁中。对大跨度桥梁进行施工监控是确保其成桥状态符合设计要求的重要措施。简要介绍了施工控制的重要性、主要内容以及影响施工控制的因素,介绍了城北大桥所采用的施工监控方法,诸如监测内容、测点布置等。为以后同类型桥梁的施工监控提供实际工程经验。

Due to its numerous advantages,prestressed concrete continuous beam bridge is widely used in urban bridge,highway bridge & railway bridge.It is an essential measure to make construction monitoring on large-span bridge to ensure the final structural state conform to the design requirements.The importances,main content as well as the factors influencing construction control are introduced briefly in this paper.Moreover,the construction monitoring & control method to Chengbei Bridge is presented in detail such as monitoring content,measuring points layout,etc.,which can provide engineering practical experience for the same bridge.
