【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,得出了同类桥梁的设计及施工控制可借鉴的结论。更多还原

【Abstract】 Based on the 1/10 scale down model test of the whole bridge of Liede Bridge in Guangzhou city, aimed at the nonlinear behaviors of self-anchored suspension bridge in its process of structural system transformation,A testing study was carried out.The paper revealed the connotative meaning and denotation of the evolution laws of the tension of hanger and the deformation of main cable and clarified the target of construction control in the process of structural system transformation,pointed out the construction control method in two construction stages,analyzed the influence laws of construction error,advanced the control and adjustment of construction error,obtained some valuable conclusions for the design and construction control of the same type bridge in the end.更多还原
