Steel box tied-arch bridge main body structure construction method
The invention relates to the field of bridge construction, especially a construction process of a steel box tied-arch bridge, and in particular to a steel box tied-arch bridge main body structure construction method. According to the method, inclined pulling and buckling method is adopted for construction, installing lattice beams, tensioning tie bars, installing bridge decks, tensioning and finally tying bars to form a bridge after a main body steel box arch is erected, and the metod is characterized in that under the condition that arch feet are not anchored, a statically indeterminate structure is converted into a statically determinate structure. The problems of foundation adaptability, full-bridge linearity, structural safety and the like in steel box tied-arch bridge main body structure construction can be effectively solved.
本发明涉及桥梁施工领域，尤其是钢箱系杆拱桥的施工工艺。具体是一种钢箱系杆拱桥主体结构施工方法，包括采用斜拉扣挂法施工，主体钢箱拱架设完成后安装格构梁，张拉系杆，安装桥面板，张拉最后系杆成桥，其特征在于在拱脚无锚固的情况下，从超静定结构转化为静定结构。能够有效解决钢箱系杆拱桥主体结构施工当中的地基适应力、全桥线性和结构安全等问题。
