Large-span arch bridge steel mixed composite shear pile
The invention relates to a large-span arch bridge steel mixed composite shear pile. The large-span arch bridge steel mixed composite shear pile comprises a reinforced concrete pile, wherein at least one profile steel is arranged in the reinforced concrete pile, and each profile steel is arranged in the length direction of the reinforced concrete pile. According to the large-span arch bridge steelmixed composite shear pile, the large-span arch bridge steel mixed composite shear pile is applied, the profile steel is arranged in the reinforced concrete pile to form the steel mixed composite shear pile, the bearing capacity of the pile to the horizontal load of an arch bridge is improved through the shear capacity of the profile steel, and the pile foundation is limited to be small by geological conditions; and the shear pile is simple in structure, high in durability, simple in construction process, short in construction period and high in construction safety degree, and can solve the problem that a conventional reinforced concrete pile has the insufficient shear capacity under the condition that the number of piles is not increased, and the investment is saved.
本发明涉及一种大跨拱桥钢混组合抗剪桩，包括钢筋混凝土桩，所述钢筋混凝土桩内设有至少一个型钢，每个所述型钢沿所述钢筋混凝土桩长度方向设置。运用本发明所述的一种大跨拱桥钢混组合抗剪桩，在所述钢筋混凝土桩内设置所述型钢形成钢混组合抗剪桩，通过所述型钢的抗剪承载力提高桩本身对拱桥水平向荷载的承载力，桩基础本身受地质条件限制小，该抗剪桩结构简单，耐久性高，施工过程简单、施工周期短、施工安全度高，能够在不增加桩数的情况下解决常规钢筋混凝土桩抗剪承载力不足而需要较大较多的群桩基础的问题，从而节省投资。
