摘要
为分析某主跨730 m钢桁架加劲梁悬索桥的受力情况,通过将静载试验实测数据和理论数据进行分析对比,结果表明该桥主体结构受力性能满足设计荷载等级要求。在试验中发现附属设施存在与主体结构变形不协调问题,其在试验荷载下存在破坏的可能。提示在类似设计时,应注意附属设施与主体结构的变形协调问题,以适应主体结构的变形要求。
The static load test of a steel truss stiffened girder suspension bridge with 730 m span is mainly introduced to analyze the mechanics performance. The comparison between measured data and theoretical data shows that the mechanical performance of main structure in bridge reaches the design load grade. However, in the course of the test, it is found that the subsidiary structure does not meet the deformation requirements of the main structure. According to the test results, the failure possibility of the subsidiary structure under test load is determined. The test enlightens the designer to pay attention to the compatibility of the deformation between the auxiliary facilities and the main structure in order to meet the deformation requirements of the main structure.
