摘    要:以江山北关自锚式悬索桥为例,利用有限元软件建立了自锚式悬索桥空间分析模型,分别考虑了恒载静力作用、主缆吊杆初始张拉力及几何非线性对其静力特性的影响。通过分析计算,给出了这些因素对该桥静力特性的影响规律。然后,通过典型的实桥静载试验研究来验证理论分析。从加劲梁、主缆挠度与索塔水平偏位,加劲梁与索塔应变,吊杆索力等几方面的对比,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。

关 键 词:自锚式悬索桥  初始平衡状态  初始张拉力  有限元法  静载试验

Abstract:Taking a self-anchored suspension bridge,Beiguan Bridge in Jiangshan,as an example,the self-anchored suspension bridge model is established using the finite element software.The behaviour of Beiguan Bridge is analyzed by considering the impact of these factors including dead load action,initial forces of the main cable and its non-linear geometry on the bridge's static characteristics.The filed static load test is completed to verify the theoretical analysis.The results show that there is a good agreement b...
Keywords:self-anchored suspension bridge  the initial state of equilibrium  the initial tensile force  limited element method  static load test
