Construction method of large-span spatial deformed steel box basket arch bridge
The invention belongs to the technical field of bridge construction, and discloses a construction method of a large-span spatial deformed steel box basket arch bridge. The method comprises the following steps: establishing an arch rib segmentation model based on historical arch rib structure data and historical arch rib segment data; determining arch rib sub-segments of the special-shaped arch rib in the target arch bridge based on the arch rib segmentation model; performing displacement analysis on the arch rib sub-segments according to preset influence factors, and determining position offset data of the arch rib sub-segments; correcting the spatial position coordinates of the arch rib sub-segments according to the position offset data to obtain target position coordinates of the arch rib sub-segments; according to the working data of the crane and the target position coordinates of the arch rib sub-segments, planning the position of the crane; and according to the position of the crane and the target position coordinates of the arch rib sub-segments, the arch rib sub-segments are hoisted. By means of the mode, the special-shaped arch ribs are accurately positioned, hoisting of the special-shaped arch ribs is optimally planned, the construction speed of the special-shaped arch ribs is increased, and the construction period of the whole basket arch bridge is shortened.
本发明属于桥梁施工技术领域，公开了一种大跨度空间异型钢箱提篮拱桥施工方法。该方法包括：基于历史拱肋结构数据与历史拱肋节段数据，建立拱肋分段模型；基于拱肋分段模型，确定目标拱桥中异型拱肋的拱肋子节段；根据预设影响因素对拱肋子节段进行位移分析，确定拱肋子节段的位置偏移数据；根据位置偏移数据对拱肋子节段的空间位置坐标进行修正，得到拱肋子节段的目标位置坐标；根据吊车工作数据与所述拱肋子节段的目标位置坐标，规划吊车站位；根据吊车站位与拱肋子节段的目标位置坐标，对拱肋子节段进行吊装。通过上述方式，对异型拱肋精确定位，并对异型拱肋的吊装进行最优规划，提高异型拱肋的施工速度，缩短整个提篮拱桥的施工周期。
