Design and construction method of low-height widened bridge
The invention relates to the technical field of bridges, in particular to a low-height widening bridge design and construction method, a through steel tied arch bridge is adopted, a mannequin lane and a motor vehicle lane on the two sides are combined into a whole in the range of the arch bridge in a gradual change mode according to the widening requirement, a herringbone main arch is arranged between the mannequin lane and the motor vehicle lane, and the herringbone main arch is arranged between the mannequin lane and the motor vehicle lane. Tie beams are connected to the two sides of a main beam of the motor vehicle lane respectively, and the tie beams are arranged on the side, close to the motor vehicle lane, of the passenger lane; arch ribs of the herringbone main arch are connected with a straining beam of the motor vehicle lane and a straining beam of the mannequin lane through suspenders, and the straining beam of the motor vehicle lane is connected with the straining beam of the mannequin lane through a cross beam. The method has the advantages that the problem of design and construction of the large-span low-height widened bridge is solved, the low-height bridge can be widened by about 30 m (specifically, the bridge span, the road widening condition and stress calculation need to be combined), the technical economy is good, the social benefit is obvious, and the application prospect is wide.
本发明涉及桥梁技术领域，尤其是一种低高度变宽桥梁设计及施工方法，采用下承式钢系杆拱桥，根据变宽要求将两侧的人非道与机动车道在拱桥范围内采用渐变的方式由三幅桥合并为整幅，在人非道与机动车道之间设置有人字型主拱，在机动车道的主梁两侧分别连接系梁，在人非道邻近于机动车道的一侧设置系梁；将人字型主拱的拱肋与机动车道的系梁以及人非道的系梁之间通过吊杆连接，将机动车道的系梁与人非道的系梁之间通过横梁连接。本发明的优点是：解决大跨度低高度变宽桥梁设计施工的难题，实现低高度桥梁30m左右的变宽（具体需结合桥梁跨度、道路变宽情况及受力计算确定），具有良好的技术经济性、社会效益明显、应用前景广阔。
