摘要
磨乡大桥主跨结构设计为钢筋混凝土箱形拱,净跨为100m,矢高为16.67m。通过对桩基、平台、临时墩、盖梁、贝雷梁、碗扣式满堂支架及模板等部位施工控制,较好地完成了施工。总结出该组合支架方案具有承载力好、安全系数高及施工工期较短等优点。
The main span structure of Moxiang Bridge is designed as reinforced concrete box arch with a clear span of 100 m and vector height of 16.67 m. Construction control is successfully realized in pile foundation and platform, temporary pier and capping beam, bailey beam, cuplock full scaffold and formwork, ensuring smooth construction, it is concluded that such combined supporting scheme has favorable bearing capacity, high safety factor and short construction schedule.
