摘要
鳌江四桥主桥为130 m+150 m的独塔双索面钢混组合梁斜拉桥。通过模型试验研究了组合梁剪力滞效应和索梁锚固构造疲劳性能两个关键技术问题,得出组合梁剪力滞系数,验证了索梁锚固结构在疲劳荷载作用下的安全性,可为桥梁设计提供参考。
The main bridge of Aojiang River Bridge IV is a 130-m + 150-m single-pylon double-plane steel-concrete composite beam cable-stayed bridge. Through the model test, two key technical problems of the shear-lag effect of composite beam and the anchorage structure fatigue performance of cable and beam are studied, the shear-lag coefficient of composite beam is concluded and the safety of cable-girder anchorage structure under fatigue loading is verified, which can be referred for the design of the similar bridges.
