背景技术Background technique

系杆拱桥是将拱与梁两种基本结构形式组合在一起,共同承受荷载,充分发挥梁受弯、拱受压的结构性能和组合作用,拱端的水平推力用拉杆承受,使拱端支座不产生水平推力。目前,以混凝土为主要材料的拱桥在营运过程中,在温度、车辆荷载等荷载作用下,拱肋跨中常会出现横桥裂缝,少数出现跨中明显下挠变形,承载能力和行车舒适性能力明显下降。Tied arch bridge is a combination of two basic structural forms of arch and beam, which jointly bear the load, give full play to the structural performance and combined effect of beam bending and arch compression, and the horizontal thrust of the arch end is supported by tie rods, so that the arch end support No horizontal thrust is produced. At present, during the operation of arch bridges with concrete as the main material, under the action of temperature, vehicle load and other loads, transverse bridge cracks often appear in the mid-span of arch ribs, and a few have obvious downward deflection in the mid-span. Significantly decreased.

现有技术中,如中国专利CN1483895A设计了一种轨道交通与城市道路一体化系杆拱桥,该系杆拱桥通过设置加劲纵梁和横梁,加劲纵梁施加纵向预应力以克服恒、活载引起的拱肋水平推力,该方法用料较多、增加基础施工费用,不易对老旧桥梁进行施工;中国专利CN101638883A设计了一种拱桥,该拱桥在桥面和拱圈之间设置多根传递载荷的构件,传递载荷的构件从拱圈成放射状延伸至桥面用来减小跨中弯矩,该方法增大了桥面的弯矩,降低了行车的舒适性。In the prior art, such as the Chinese patent CN1483895A, a tie-bar arch bridge integrated with urban roads is designed. The tie-bar arch bridge is provided with stiffened longitudinal beams and beams, and the stiffened longitudinal beams are applied longitudinal prestress to overcome the constant and live loads. The horizontal thrust of the arch rib, this method uses more materials, increases the cost of foundation construction, and is not easy to construct the old bridge; Chinese patent CN101638883A designs an arch bridge, and the arch bridge is provided with multiple load-transferring bridges between the bridge deck and the arch ring The components that transmit the load extend radially from the arch ring to the bridge deck to reduce the mid-span bending moment. This method increases the bending moment of the bridge deck and reduces the driving comfort.
