对采用柔性排架桩的公路桥梁,配置橡胶支座并适宜的布置,能将温度力、制动力和水平土压力,比较合理地分配到各个柔性排架桩墩台。使桩的断面、配筋设计计算比较经济合理。在计算公式的推导过程中,考虑了橡胶支座的刚度、桩的刚度、土对桩的弹性抗力等因素。并假定:1.桩的下端为弹性嵌固,桩的上端可按自由,也可按弹性嵌固。2.采用橡胶支座时,允许上部结构对桩顶发生相对位移,但不允许橡胶支座发生滑动。如果采用橡胶支座和油毛毡支座配合放
For the bridge and bridge with flexible pile-supported piles, the rubber bearings are arranged and arranged properly, which can distribute the temperature force, braking force and horizontal earth pressure more reasonably to each flexible pile-pier. Make pile section, reinforcement design calculation more economical and reasonable. In the derivation of the formula, the factors such as the stiffness of the rubber bearing, the stiffness of the pile and the elastic resistance of the pile to the pile are taken into account. And assume: 1. The lower end of the pile is elastic embedded, the upper end of the pile can be free, but also can be embedded by elasticity. 2. When using rubber bearings, relative displacement of superstructure to pile top is allowed, but rubber bearings are not allowed to slide. If using rubber bearings and oil felt holder with the release
