Construction method of asymmetric large-span arch bridge
The invention provides a construction method of an asymmetric large-span arch bridge, which comprises the following steps of: 1) constructing a temporary bracket foundation and installing a temporary bracket on a main-span bridge floor; (2) mounting buttresses in a main-span main beam and a bridge floor steel structure, and mounting a main-span main arch bracket and an arch section; (3) mounting a main-span main beam and a bridge floor steel structure, and mounting a main-span arch rib bracket and an arch rib; (4) dismantling a main span arch rib support, hoisting a main span residual bridge floor steel structure, and installing and tensioning a main span suspender; the method comprises the following steps of (1) installing a bridge deck support, (2) dismantling a main span support, erecting a side span main beam support, installing a side span bridge deck steel structure, and installing a side span arch rib support and an arch rib, (3) dismantling the side span arch rib support, hoisting a residual side span bridge deck steel structure, installing and tensioning a side span suspender, and dismantling the side span bridge deck support, and (4) carrying out a finished bridge load test and completion traffic according to supports on two sides of a middle pier, bridge deck pavement and accessory arrangement.
本发明提供了一种非对称大跨度拱桥的施工方法，包括以下步骤，1）临时支架基础施工以及主跨桥面临时支架安装；2）主跨主梁中支墩和桥面钢结构安装，以及主跨主拱支架与拱节段安装；3）主跨主梁与桥面钢结构安装以及主跨拱肋支架与拱肋安装；4）拆除主跨拱肋支架、吊装主跨剩余桥面钢结构，主跨吊杆安装并张拉；5）拆除主跨支架、架设边跨主梁支架，边跨桥面钢结构安装，边跨拱肋支架与拱肋安装；6）边跨拱肋支架拆除，吊装边跨剩余桥面钢结构，边跨吊杆安装并张拉，边跨桥面支架拆除。7）按照中墩两侧支座，桥面铺装及附属设置，进行成桥荷载试验，竣工通车。
