弯塔斜拉桥静力性能模型实验研究

Analysis on the Landform and Formation Lithology of Zihong Reservoir

为了研究混合梁弯塔斜拉琴桥的结构性能,设计制作了其全桥缩尺模型并进行了静载测试,通过不同工况下选取截面的应力和挠度值与有限元分析结果的对比,发现二者吻合较好,证明有限元分析结果是准确的,同时说明所建立的有限元模型较真实地反映了琴桥的实际结构特性,可以为该桥的进一步设计及施工监控提供理论指导。

In order to study the structural properties of cable-stayed bridge with bent tower and hybrid beam, tins paper makes the scale model of the whole bridge and carry out the static test, through the comparison of finite element analysis data with experimental stress and deflection values ＂about the selected sections under different cases, demonstrates that the results are in good agreement with each other, which proves that the results of finite element analysis are accurate, and the established finite element model reflects the real structural properties of the bridge and can provide a theoretical guidance for future design and construction control.
