Large-span corrugated steel-concrete composite structure shed tunnel and construction method thereof
The invention relates to a large-span corrugated steel-concrete composite structure shed tunnel and a construction method thereof. According to the large-span shed tunnel with the corrugated steel-concrete combined structure, deformation of the two sides of the corrugated steel-concrete combined arch ring can be reduced by arranging the filling layers, and the structural stability is guaranteed; a horizontal top reinforcing mesh is arranged in a filling layer above the top of a corrugated steel-concrete combined arch ring, main load-bearing steel bars are arranged in the direction perpendicular to the axial direction of a shed tunnel, and the top reinforcing mesh, the filling layer and the corrugated steel-concrete combined arch ring are stressed together to form a deck-like beam-arch combined stress system. Meanwhile, horizontal anchoring steel bars are arranged on the two sides of the corrugated steel-concrete combined arch ring, the corrugated steel-concrete combined arch ring and the filling layer concrete on the two sides are anchored into a whole through the horizontal anchoring steel bars, and the overall stability and stress performance of the shed tunnel are further improved; and the protection requirement of a larger-span shed tunnel can be met.
本发明涉及一种大跨度波纹钢‑混凝土组合结构棚洞及其施工方法。一种大跨度波纹钢‑混凝土组合结构棚洞，通过设置填充层能够减小波纹钢‑混凝土组合拱圈两侧的变形，保证结构稳定；且通过在波纹钢‑混凝土组合拱圈顶部上方填充层内设置水平的顶部钢筋网，其中垂直棚洞轴向方向为主受力钢筋，顶部钢筋网、填充层与波纹钢‑混凝土组合拱圈共同受力，形成类似上承式梁拱组合受力体系，大大提高了大跨度波纹钢棚洞的抗冲击和承载力性能，同时波纹钢‑混凝土组合拱圈两侧设置水平锚拉钢筋，水平锚拉钢筋将波纹钢‑混凝土组合拱圈与两侧填充层混凝土锚固成整体，进一步提高了棚洞的整体稳定性与受力性能，使得能够满足更大跨度的棚洞防护需求。
