上承式箱型混凝土拱桥荷载试验分析

Loading Test Analysis for Upper Bearing Box Concrete Arch Bridge

通过对恩施市连珠大桥进行静载、脉动和现场荷载试验,测得结构的各种力学指标和性能指标,并与理论计算值及相应的规范规程要求进行了对比,从而对桥梁的整体性能和结构的安全性做出了评价。试验结果表明,该桥的主体结构满足设计要求,达到了设计要求的承载能力。

Through the static load test,fluctuation test and site load test of enshi Lianzhu Bridge,the paper got the various mechanical indexes and performance indicators,which were compared with the theoretical calculation values and the corresponding standard requirements,thus the bridge＇s overall performance and structure security was assessed.The results show that the main structure of the bridge meets the design requirements and the design requirements of the carrying capacity.
