Large-span deck type concrete-filled steel tube arch bridge
The invention relates to a large-span deck type concrete-filled steel tube arch bridge. The concrete-filled steel tube arch bridge comprises a main arch, web arches, a junction pier, a bridge deck beam and a main arch spandrel column. The web arches are arranged on the two sides of the main arch in the longitudinal bridge direction respectively. In any side of the main arch, the web arch is divided into a first web arch and a second web arch, the first web arch is fixedly connected with a web arch support and the junction pier, the second web arch is connected with the junction pier, the mainarch and/or the main arch spandrel column, and the main arch spandrel column, the junction pier and the web arch jointly support the bridge deck beam. By means of the arrangement, the overall height of the main arch spandrel column is reduced, the dead weight of the bridge body is reduced to a certain degree, the stress requirement of the main arch is met, meanwhile, the engineering difficulty andthe engineering manufacturing cost are reduced, and the stability of the bridge body is improved. In addition, the web arch forms a longitudinal connecting structure between the main arch spandrel columns, and the longitudinal bridge direction stability of the main arch spandrel columns is further improved.
本发明涉及一种大跨径上承式钢管混凝土拱桥。所述钢管混凝土拱桥包括主拱、腹拱、交界墩、桥面梁和主拱拱上立柱。所述腹拱沿纵桥向分设于所述主拱的两侧。所述主拱的任一侧中，所述腹拱分为第一腹拱和第二腹拱，所述第一腹拱与腹拱拱座和所述交界墩固定连接，所述第二腹拱与所述交界墩、主拱和/或所述主拱拱上立柱连接，所述主拱拱上立柱、交界墩和腹拱共同支承所述桥面梁。通过上述设置，所述主拱拱上立柱的整体高度降低，一定程度上降低桥身自重，以满足所述主拱的受力要求，同时还降低了工程难度和工程造价，并提升桥身稳定性。另外，所述腹拱在所述主拱拱上立柱之间形成纵向连接结构，还提升了所述主拱拱上立柱的纵桥向稳定性。
