摘　　要：以独塔单索面预应力混凝土斜拉桥静荷载试验结果为依据,通过对静荷载试验工况下控制截面的斜拉索索力增量、主塔塔顶偏位、主梁挠度和截面应力等重要测试数据的分析,并结合理论计算结果来研究不同荷载试验工况下斜拉桥的索力变化规律、强度和刚度等特性。Based on static load test result of pre - stressed concrete cable stayed bridge with single tower and single cable plane and combined with theoretical calculation result, characteristics of cable stayed bridge like cable force change rules, strength and rigidity under different working conditions of load test are studied through analyzing significant test data of control section under working condition of static load test, such as cable force increment, off normal of main tower top, deflection of main beam and cross section stress.
