摘　　要：本文通过建立大型实体悬索桥模型试验,划分对称性测点38个,测试在不同荷载下悬索杆及支点反力。研究分析在各种荷载下支反力分布规律和桥拱的受力情况。得出:拱圈承担了模型的大部分荷载,当荷载施加在模型的边缘和端部时,模型承受的荷载更为集中,拱圈和桥面横梁的交接点是多种加载方案下支反力集中体现的关键部位。In the present work, based on suspension-bridge, the model test of is established, and the 38 symmetry testing points are divided to test the reaction forces of suspension cables and fulcrum under different loads. The distribution law of support reaction and the stress of bridge arch under various loads are studied and analyzed. The results indicated that load is mainly focused on the arch ring, and become concentrated when the load is applied on edge and end of the model. Also, the intersection of arch ring and bridge deck beam is the key location of the reaction force under various loading.
