Simply supported-to-continuous composite beam bridge structure capable of improving crack resistance of bridge deck slab in hogging moment area
The invention relates to a simply supported continuous composite beam bridge structure capable of improving the crack resistance of a bridge deck slab in a hogging moment area, which comprises bridge abutments on two sides and a plurality of piers distributed between the bridge abutments on the two sides along the longitudinal direction of a bridge, and a composite beam structure is arranged between the bridge abutments on the two sides and the tops of the piers. The combined beam structure comprises a plurality of steel-concrete combined beams which are spliced in the transverse bridge direction, arch-shaped inhaul cable structures protruding upwards are arranged at the positions, between the bridge abutment and the bridge piers, of the lower portion of the combined beam structure and between the adjacent bridge piers, and the protruding tops of the inhaul cable structures are anchored in the midspan of the combined beam structure. The bottoms of the two ends of the inhaul cable structures located between the bridge abutment and the bridge piers are anchored to the bridge abutment and the bridge piers correspondingly, and the bottoms of the two ends of the inhaul cable structures located between the adjacent bridge piers are anchored to the bridge piers. The method is simple in structure, reasonable in design, lower in cost, simpler and quicker in construction, and capable of preventing the hogging moment concrete slab from cracking and improving the durability of the structure.
本发明涉及一种提升负弯矩区桥面板抗裂性能的简支转连续组合梁桥结构，包括两侧桥台、沿纵桥向分布在两侧桥台之间的若干个桥墩，两侧桥台和若干个桥墩的顶部之间设有组合梁结构，所述组合梁结构包括若干个沿横桥向拼接的钢‑混凝土组合梁，组合梁结构的下部于桥台与桥墩之间、相邻桥墩之间均设置有向上凸起的拱形状拉索结构，所述拉索结构凸起的顶部锚固在组合梁结构的跨中，位于桥台与桥墩之间的拉索结构的两端底部分别锚固在桥台和桥墩上，位于相邻桥墩之间的拉索结构的两端底部均锚固在桥墩上。本发明结构简单、设计合理，成本更为低廉，施工更为简单、快速，可防止负弯矩混凝土板的开裂，提升结构的耐久性能。
