框架式排架桩桥,能利用桥头填土对桥上水平力的抵抗作用,削减排架桩的计算弯矩,降低桩内的钢筋用量;这种桥不用设置桥面的温度伸缩缝,可以避免行车过缝的跳车问题,还能提高抗震能力,方便养护,降低造价。这种桥的适用长度为50～80米。 Frame-type pile traversed bridge can take advantage of bridgehead filling on the horizontal force of the bridge to reduce the calculated bending moment of pile, reducing the amount of steel inside the pile; this bridge without setting the bridge deck temperature expansion joints, you can Avoid jumping over the traffic trip problem, but also improve the seismic capacity, easy maintenance, reduce costs. This bridge is 50 to 80 meters long.
