大跨度不对称桥梁施工控制及施工措施

Construction Control and Construction Measures of Large Span Asymmetric Bridges

对大跨度不对称桥梁施工及运营中的各项挠度和位移进行了分析,详细介绍了用以指导施工的施工立模标高的计算方法。针对桥的不对称特性,对主要构件的施工和重要施工步骤提出了施工措施建议,保证了安全顺利地完成桥梁施工。

This paper analyzed the deflection and displacement of the large span asymmetric bridges during the construction and using, and introduced detailed method about how to calculate the elevation of the moulding boards set method, which can be used to guide the construction. Because the bridge is asymmetric, this paper proposed some suggestions about construction measures for some important components and processes to ensure the bridge could be constructed safely.
