小半径悬浇曲线桥的施工监控技术

Construction Monitoring Technique of Small Radius Curved Bridge with Cantilever Casting

以台江大桥悬浇桥施工为例,简单介绍在小半径悬臂浇筑施工的桥梁中,采用预埋温度及内力应变传感器,结合施工监控测量,通过先进的计算软件,控制施工的线形,确保桥梁内力达到设计要求,顺利合拢。

With the example of cantilever casting construction of Taijiang bridge, the paper introduces the control of small radius bridge with cantilever casting construction by installing temperature and stress sensor inside bridge, monitoring and measuring, controlling the alignment as well as calculation of advanced software to guarantee the stree of bridge to fulfil the designing requirements and the bridge structure to close uo smoothly.
