Large-span three-connected arch bridge
The invention discloses a large-span three-continuous arch bridge, and belongs to the technical field of bridge engineering. The large-span three-continuous arch bridge comprises a main beam and two arch ribs, wherein each arch rib corresponds to two middle piers and two side piers; each arch rib comprises a middle span, two side spans and two span legs, the tops of the middle spans and the tops of the two side spans are fixedly connected, the two ends of the middle spans and one ends of the corresponding side spans are fixed to the corresponding middle piers respectively, and one ends of the middle spans and one ends of the corresponding side spans are fixedly connected with the main beam; the other ends of the side spans and the bottom ends of the corresponding span legs are fixed to the side piers, cross beams are connected between the two oppositely-arranged side spans and between the top ends of the two span legs, and supports are arranged on the cross beams. According to the large-span three-continuous arch bridge provided by the embodiment of the invention, the main beam and the arch ribs can be reliably supported, the horizontal thrust formed at the bottom of the midspan can be reduced, meanwhile, expansion joints do not need to be arranged on the main beam, and the durability of the main beam is enhanced.
本发明公开了一种大跨度三连拱桥，属于桥梁工程技术领域。所述大跨度三连拱桥包括主梁和两个拱肋，各所述拱肋对应两个中墩和两个边墩；各拱肋包括中跨、两个边跨和两个跨腿，且中跨和两个边跨的顶部均固定连接，中跨的两端分别和相对应的边跨的一端固定在相对应的中墩上，中跨的一端和相对应的边跨的一端均与主梁固结，边跨的另一端和相对应的跨腿的底端固定在边墩上，相对布置的两个边跨之间和两个跨腿的顶端之间均连接有横梁，且各横梁上均设置有支座。本发明实施例提供的一种大跨度三连拱桥，不仅可以对主梁和拱肋的可靠支撑，还能减小中跨底部形成的水平推力，同时主梁上无需设置伸缩缝，增强了主梁的耐久性。
