预应力混凝土连续梁不平衡施工及监控技术研究

Study on Unbalanced Construction and Monitoring Technologies of Prestressed Concrete Continuous Beam

受环境条件的制约和影响,预应力混凝土连续梁结构形式各异,给悬臂挂篮法施工带来一定的困难。结合宜宾市大溪口至南广交通改造及景观工程,对预应力混凝土连续梁不平衡施工以及监控技术进行研究和阐述。同时根据实践,总结了不平衡施工控制的关键技术和工艺,对类似工程具有一定的借鉴意义。

Restricted and influenced by the environment conditions,the prestressed continuous concrete beam has various forms of structure,which brings certain difficulties to cantilever hanging-basket construction method.Combined with the traffic renovation and landscape engineering from Da Xikou to Nanguang in Yibin City,the unbalanced construction and monitoring technique during construction of prestressed continuous concrete beam are studied and elaborated.At the same time,according to the practice,the key technologies and processes of unbalanced construction control are also summarized in this paper,which have certain reference significance for similar projects.
