摘 要本设计是对一个 15 米先张法混凝土预应力空心简支板桥的验算与设计。设计书拟定了桥梁的上部结构及其尺寸，并对内力进行计算。我的桥梁计算书也对其中主要的构件逐一分别的进行了一般使用时的强度承载力时的极限状态的计算和极限状态的计算。在这之中，上部结构的尺寸主要基于桥梁和涵洞规格以及其他相关示例。 横向分配系数也是通过杠杆原理方法和铰板方法获得。 并且参考相关实例，将 10 个中空板分组，然后知道水平分布影响线，最终得到横向分布系数。关键词：空心板，预应力，简支梁AbstractThis design is a check and design of a 15m pretensioned concrete prestressed hollow simply supported bridge.The design book outlines the upper structure of the bridge and its dimensions, and calculates the internal forces. This design book also checks the limit state of the main components when they are limit state in normal use and strength carrying capacity. Among them, the size of the superstructure is mainly referred to the bridge and culvert specification and other related examples. The lateral distribution coefficient is obtained by the lever principle method and the hinge method.Referring to thee relted exaples, the 10 hollow plates are grouped, and then the horizontal distribution influence line is known, and the lateral distribution coefficient is finally obtained.Key words: hollow slab, prestressed, simply supported beam目录Abstract ..................................................................................................................................................... 3 1 设计资料 ................................................................................................................................................. 4 1.1 、 地址水文资料 ......................................................................................................................... 4 1.2 、工程概况 ...............................................................
