Arch bridge prestress foundation and construction method thereof
The invention discloses an arch bridge prestress foundation and a construction method thereof.The arch bridge prestress foundation comprises a fender post structure, a top beam structure, an arch foot steel pipe structure, arch foot concrete and a waist beam, and the fender post structure is formed by meshing a circular pile foundation, a special-shaped pile foundation and a prestress pile foundation; arc-shaped indents are formed in one side/two sides of the special-shaped pile foundation to be matched with the circular pile foundation and the prestressed pile foundation, the prestressed pile foundation is arranged on the side close to the arch foot steel pipe structure, and the prestressed pile foundation is a circular high-strength concrete pile provided with prestressed steel bars. According to the arch bridge prestressed foundation, the prestressed secant piles are adopted as important components of the integral arch foot foundation, bending moment generated by horizontal thrust of arch feet on the front pile foundation can be balanced, the stress characteristics of the foundation are changed, different pile types are adopted for assembling according to the stress characteristics of the structure to adapt to and optimize the geometric dimension of the foundation, the construction period is shortened, and the construction cost is reduced. And economic benefits are brought.
本发明公开了一种拱桥预应力基础及其施工方法，其中拱桥预应力基础包括围护桩结构、冠梁结构、拱脚钢管结构、拱脚混凝土和腰梁，所述围护桩结构由圆形桩基、异形桩基和预应力桩基咬合而成，所述异形桩基的一侧/两侧设有弧形内凹以适配所述圆形桩基、所述预应力桩基，其中所述预应力桩基设置于靠近所述拱脚钢管结构一侧，所述预应力桩基为圆形的设有预应力钢筋的高强混凝土桩。本发明所提供的拱桥预应力基础采用预应力咬合桩作为整体式拱脚基础的重要组成部分，可平衡前置桩基受拱脚水平推力产生的弯矩，改变基础受力特性，根据结构受力特点采取不同桩型的组配来适应，优化基础几何尺寸，缩短施工周期，带来经济效益。
