Highway-railway same-layer single-cable-plane concrete extradosed cable-stayed bridge
The invention discloses a highway-railway dual-purpose same-layer single-cable-plane concrete extradosed cable-stayed bridge. The width of the highway-railway dual-purpose same-layer bridge is large, so that the transverse width of a bridge tower is large. A bridge tower upper tower column is fixedly connected to the upper portion of the middle of a main beam, a bridge tower lower tower column is fixedly connected to the lower portion of the middle of the main beam, and the main beam and the bridge tower upper tower column are connected through a single-cable-plane stay cable; a road traffic lane and a railway traffic lane are respectively arranged on two sides of the upper tower column; two transverse partition beams are respectively arranged at the fixedly connected parts of the main beam and the upper tower column and the lower tower column; longitudinal dampers and transverse dampers are arranged at the positions, connected with the bridge piers through supports, between the main beams and the bridge piers. The lower tower column of the bridge tower is provided with the left thin wall and the right thin wall which are connected through the cross beam, and the problem that the lower structure of the bridge tower structure is huge is solved; the upper tower column is divided into two tower columns which correspond to the two thin-wall tower columns of the lower tower column, two transverse partition plates are arranged at the fixedly connected positions of the upper tower column and the lower tower column and the main beam, and the problem of force transmission is well solved.
本发明公开了一种公铁两用同层单索面混凝土矮塔斜拉桥。公铁两用同层桥梁宽度大，导致桥塔横向宽度大。本发明主梁中部上方固结有桥塔上塔柱，下方固结有桥塔下塔柱，主梁和桥塔上塔柱之间通过单索面斜拉索连接；上塔柱两侧分别设有公路行车道和铁路行车道；主梁与上塔柱和下塔柱固结处分别设有两道横隔梁；主梁与桥墩之间通过支座连接支座位置处设有纵向和横向阻尼器。本发明将桥塔下塔柱设置为左右两个薄壁，通过横梁连接，解决了桥塔结构下部结构庞大的难题；上塔柱岔分为两个塔柱，与下塔柱两个薄壁塔柱对应，上下塔柱与主梁固结处设置两道横隔板，很好地解决了传力问题。
