番禺大桥斜拉桥的施工控制

番禺大桥主桥采用空间双索面预应力混凝土斜拉桥结构体系，该大桥主跨380m，桥宽37．7m。由于主梁梁高低、刚度柔、节段量，主桥采用了牵索挂篮悬臂浇筑施工。本文介绍了该斜拉桥施工过程的模拟分析、主梁线形和斜拉索拉力的调整和控制方法。番禺斜拉桥的施工控制结果表明：通过对斜拉桥施工过程的仔细模拟计算和连续监测，可以及时掌握斜拉桥受力状况，并达到较高的控制精度。

Construction Control for the Panyu Cable-Stayed Bridge

This paper presents the methods used to simulate the erection process, monitor the girder profile and adjust cable tensions of the Panyu Cable_Stayed Bridge. The bridge with 380 meters long of the main span is built using the balanced cantilever construction method. The bridge segments are cast in_situ on traveller forms. Due to the flexibility of deck, cable_supported carriages are used. It brings more difficulty into the construction control. Thus, it is important to carry out careful and detailed simulation of the construction processes. It shows that detailed calculation and continuous monitoring of the erection process can give good knowledge of the static behaviour of the actual bridge.
