介绍了国内第一座双层桥面城市桥梁——钱江四桥施工控制技术的应用及其成果,采用的施工控制技术及计算理论,不仅确保了大桥的施工期安全,而且结构内力状态与结构线性的监测结果与施工控制预测值符合较好,得到的结论可作为今后同类桥梁设计与施工的重要参考。 This paper introduces the application and achievement of the construction control technology of Qianshan No.4 Bridge, the first double decker bridge urban bridge in China, the construction control technology and calculation theory adopted, which not only ensures the safety during the construction period of bridge, but also the internal force state and structural linearity The monitoring results are in good agreement with the predictions of construction control, and the conclusions can be used as an important reference for the design and construction of similar bridges in the future.
