摘　　要：连续梁施工中,挂篮设计和施工监控是施工中的关键环节,而线性控制更是施工中的重中之重。318国道湖州南浔至吴兴段改建工程中白米塘大桥主桥采用三跨连续梁设计,施工中存在桥面跨度、宽度均较常规连续梁尺寸大,受力较为复杂,挂篮模板设计、加工难度大等主要技术难题。论文结合白米塘大桥主桥连续梁的施工,阐述挂篮模板设计及施工监控方法。In the reconstruction project of Nanxun to Wuxing section of 318 National Highway, the main bridge of Baimitang Bridge adopts the design of three-span continuous beams. The main technical problems in the construction are as follows: the span and width of the bridge deck are larger than that of the conventional continuous beams, the force is more complex, and the design and processing of hanging basket template are difficult. In continuous beam construction, basket design and construction monitoring are the key links, and linear control is the priority among priorities. In this paper, combined with the construction of the continuous beam of the main bridge of Baimidang Bridge, the design and construction monitoring methods of the hanging basket template are expounded,the successful completion of handover and acceptance of the closure has a strong reference significance for similar projects.
