城市桥梁墩柱预制拼装关键技术研究

Research on the Key Technology of Prefabrication and Assembly of Urban Bridge Pier

桥梁建设过程中,传统桥梁墩柱现浇施工技术存在一系列问题,对现场施工存在不利影响,给城市桥梁工程建设带来了更大的矛盾和隐患。而城市桥梁墩柱预制拼装技术不仅解决了传统现浇施工中的问题,还能有效缩短施工周期,为城市桥梁工程建设提供便利,减少桥梁建设对城市交通的影响。论文叙述了城市桥梁墩柱预制拼装技术方式,从设计连接结构、力学性能、地震灾害问题3方面对城市桥梁墩柱预制拼装技术进行了研究。

In the process of bridge construction,there are a series of problems in the traditional cast-in-situ construction technology of bridge piers and columns,which have adverse effects on the on-site construction,and bring greater contradictions and hidden dangers to the construction of urban bridges.The prefabrication and assembling technology of urban bridge piers and columns not only solves the problems in the traditional cast-in-place construction,but also effectively shortens the construction period,facilitates the construction of urban bridges,and reduces the impact of bridge construction on urban traffic.This paper describes the prefabrication and assembling technology of urban bridge piers and columns,and studies the prefabrication and assembling technology of urban bridge piers and columns from three aspects:design of connection structure,mechanical properties and earthquake disaster.
