摘要
依据广州猎德大桥1/10比例的全桥模型试验,针对自锚式悬索桥体系转换过程中的非线性行为作了相关的试验研究,揭示了体系转换过程中吊索索力、主缆变形演变规律的内涵与外延,阐明了体系转换过程中的施工控制目标,指出了自锚式悬索桥两阶段施工控制方法,分析了施工误差的影响规律,提出了误差控制与调整方法,得出了同类桥梁的设计及施工控制可借鉴的结论。
Based on the 1/10 scale down model test of the whole bridge of Liede Bridge in Guangzhou city, this paper investigated the nonlinear behaviors of self-anchored suspension bridge in its process of structural system transformation. The paper presented the development of the tension of hanger and the deformation of main cable, and clarified the goal of construction control in the process of structural system transformation. The construction control method in two construction stages was proposed. The paper analyzed the influence of construction error, and suggested the construction error be controlled and adjusted. Some valuable conclusions were drawn for the design and construction control of the same type of bridge.
