| 摘 要： | 针对目前对自锚式悬索桥试验研究较少的现状,以江山北关自锚式悬索桥为例,进行初始平衡状态分析,利用有限元软件建立了自锚式悬索桥空间分析模型,考虑了主缆吊杆初始张拉力影响,分析该桥的静动力特性。然后,通过典型的实桥静动载试验研究来验证理论分析,结果表明理论计算值和实测值吻合较好,北关大桥的刚度和强度满足规范要求。

| Abstract: | In light of few study on self-anchored suspension bridge load test,we take a self-anchored suspension bridge-Beiguan Bridge as an example.The initial equilibrium state is analysed,then the self-anchored suspension bridge model is established using the finite element software.Considering the impact of initial forces of the main cable,the static and dynamic behaviour of Beiguan Bridge is analyzed.The filed static and dynamic load test is completed to verify the theoretical analysis.The results show that there... |
