Standardized construction method of composite beam partial cable-stayed bridge
The invention relates to a standardized construction method of a composite beam partial cable-stayed bridge. Presetting bridge standard span schemes, determining partial cable-stayed bridge sizes according to the obstacle sizes, and selecting similar schemes from the preset bridge standard span schemes according to the determined partial cable-stayed bridge sizes; steel plate composite beam cross section size schemes are preset, the width of a bridge is determined, and an appropriate scheme is selected from the preset steel plate composite beam cross section size schemes; calculating the sectional area of a cantilever arm lacing wire for fixing the cantilever arm and the size of a cantilever arm supporting rod fixing groove; and prefabricated parts are prepared, and construction is conducted. Compared with the prior art, the design process can be rapidly completed through the standardized span and the standardized cross section, a large amount of time is saved, and economical efficiency is high. The anti-seismic and high-toughness bridge has high anti-seismic toughness, when a bridge is damaged in an earthquake, damaged components can be rapidly replaced after the earthquake, and it is ensured that traffic is rapidly recovered.
本发明涉及一种组合梁部分斜拉桥标准化建造方法。预设桥梁标准跨径方案，根据障碍物尺寸确定部分斜拉桥尺寸，并根据确定的部分斜拉桥尺寸从预设的桥梁标准跨径方案中选取相近方案；预设钢板组合梁横截面尺寸方案，确定桥梁宽度，并从预设的钢板组合梁横截面尺寸方案中选取合适方案；计算用于固定挑臂的挑臂拉筋的截面积和挑臂支撑杆固定槽的尺寸；制备预制构件并进行施工。与现有技术相比，本发明通过标准化跨度以及标准化横截面可快速完成设计流程，节省大量的时间，经济性较高。本发明具有高抗震韧性，当桥梁在地震中产生损伤后，震后可快速对损伤的构件进行更换，确保快速恢复交通。
