摘要
介绍福州市螺洲大桥试验模型的设计、试验过程和试验研究结果.通过对实测结果与有限元计算结果的分析对比,研究三塔自锚式悬索桥这一新型结构形式的静力行为.结果表明,三塔自锚式悬索桥的结构变形和内力与外荷载基本呈线性关系,主梁挠度与主塔的水平位移之间存在密切关系,主塔刚度对多塔自锚式悬索桥的竖向刚度影响较大.
This thesis introduces the model design,test process and test results of Luozhou bridge in Fuzhou.And some research has been done in the static behavior of a new type of structure,the structure of self-anchored suspension bridge with three towers,by analyzing the test results and FEM results.The results show that the relationship between reflection of self-anchored suspension bridge with three towers and load is linear.Vertical deflection of girder is closely related to horizontal deflection of tower top,and the stiffness of tower has important effect on vertical stiffness of self-anchored suspension bridge with multi-tower.
