Arch bridge thrust foundation structure and pouring method of arch bridge thrust foundation structure
The embodiment of the invention provides an arch bridge thrust foundation structure and a pouring method of the arch bridge thrust foundation structure, and relates to the technical field of bridge construction. The arch bridge thrust foundation structure comprises an open caisson foundation, an arch support, an arch rib and a plurality of grouting pile foundations, and the multiple grouting pile foundations are arranged on the lower portion of the open caisson foundation. Through an open caisson and pile composite structure, the structural strength is improved. The open caisson foundation is an integral rigid foundation, the contact area with a foundation is large, the integrity is high, the rigidity is high, and the horizontal force resistance is large; and vertical pile foundations are high in vertical force resistance. According to the open caisson and pile composite foundation, the stress characteristics of the two structures are fully utilized, respective advantages are exerted, meanwhile, compared with full open caisson foundations, the construction difficulty is reduced, and economic benefits are improved; and compared with full vertical pile foundations, the overall rigidity of the foundation is increased, so that the calculation structure is safer and more reliable.
本发明的实施例提供了一种拱桥推力基础结构和拱桥推力基础结构的浇筑方法，涉及桥梁建筑技术领域，该拱桥推力基础结构包括沉井基础、拱座、拱肋和多个灌桩基础，在沉井基础下部设置多个灌桩基础，通过沉井+桩的复合结构，增加结构强度。其中沉井基础为整体刚性基础，与地基接触面积大，整体性强、刚度大、抵抗水平力能力强；竖直桩基础抵抗竖向力能力强。沉井+桩复合基础充分利用了这两种结构的受力特点，发挥各自优势，同时比全沉井基础减小了施工难度，提高了经济效益；比全竖直桩基础，因为增加了基础整体刚度，使计算结构更加安全可靠。
