摘　　要：以杭州市无冲突、无交组运行的完全互通式中兴立交桥工程为背景,针对下两层提前开通运营后,为了满足上3层和上4层结构施工需求,同时要保证营运车辆的安全。通过对六四式军用梁进行分析与研究,简化支架结构,建立力学模型,采用杆系有限元进行受力分析,结合理论试验确定了施工支架预拱度和变形控制方法。In this paper, taking Hangzhou city without conflict and completeinterchange Zhongxing group operation of the overpass bridge project as the background, according to the opening and operation of two layer in advance, in order to meet the three layer and the four layer structure construction requirements,at the same time to ensure the safety operation of the vehicle. Through analysis and study of six four type military beam supporting structure, a simplified mechanical model was established, using, bar system finite element stress analysis, combined with the theory of testing to determine the construction frame precamber and deformation control method.

关 键 词：互通式立交桥 军用梁 变形控制
