Ultra-large span pull rod arch underground composite structure and construction method thereof
The invention relates to an ultra-large span pull rod arch underground composite structure and a construction method thereof. A large-span open-cut box type tunnel structure has the problems of large structure size, multiple structure cracks, complicated internal stress distribution, large settlement deformation due to nonuniformity and the like. The structure comprises a box-shaped structure, a pull rod arch structure and a pile foundation, the pull rod arch structure is located at the top of the box-shaped structure, and the pile foundation is located at the bottom of the box-shaped structure; the pull rod arch structure comprises a horizontal supporting plate, a pull rod and an arch top plate, the arch top plate is in an arch shape and located above the horizontal supporting plate, and the pull rod is vertically connected between the arch top plate and the horizontal supporting plate. A combined structure of the pull rod arch structure, the longitudinal hidden beams and the bottom pile foundation is additionally arranged in the tunnel box type structure, the work amount is small, a stress system is clear, the structural rigidity and stability are obviously improved, the size and deformation settlement of structural components are reduced, and the structural safety is improved.
本发明涉及一种超大跨拉杆拱地下组合结构及其施工方法。大跨度明挖箱型隧道结构存在结构尺寸大、结构裂缝多、内部应力分布复杂、不均匀沉降变形大等问题。本结构包括箱型结构、拉杆拱结构和桩基，拉杆拱结构位于箱型结构的顶部，桩基位于箱型结构的底部；拉杆拱结构包括水平支撑板、拉杆和拱部顶板，拱部顶板呈拱形并位于水平支撑板上方，拉杆竖向连接在拱部顶板和水平支撑板之间。本发明在隧道箱型结构中增加了拉杆拱结构、纵向暗梁以及底部桩基础的组合结构，工程量小，受力体系明确，并明显提升了结构刚度和稳定性，减小了结构构件尺寸和变形沉降，提高了结构安全性。
