摘要
金沙大道跨雄溪河大桥主桥为三跨预应力混凝土刚架拱桥,主跨40m。介绍了雄溪河大桥的主要技术标准、结构尺寸。重点介绍了全桥整体结构的建模过程,上部结构主梁的正、斜截面抗裂验算,正截面压应力验算,斜截面主压应力验算等静力计算分析。
The main bridge of Xiongxi River Bridge is a three-span pre-stressed concrete rigid-frame arch bridge.Its main span is 40 m.The article introduces the main technical standards and structural dimensions of Xiongxi River Bridge,and focuses introduction on the modeling process of the integral structure,the positive,oblique section crack resistance check calculation of the main girder of the superstructure,and the static calculation analysis of the positive section compressive stress check calculation and the oblique section principal compressive stress check calculation of the whole bridge.
