摘要随着社会经济的发展，桥梁工程得以迅速发展，设计思想和施工技术都得到很大的提高。本设计的桥梁是张家港市主要干道上的一座桥板，该桥跨越河道，无通航要求。设计这座桥梁运用所学的理论知识，通过计算机出图。本设计对于我有很大的启发，设计一座桥梁要从实际出发，必须先进行调查，了解设计目的，对不同的桥型进行比较，最后采用最合理的方案。根据实际情况，不同的交通量，不同的需求，从而选择最佳设计，本桥选择为空心板桥，属于中小桥梁。本设计，计算了空心板截面特性，以及空心板的作用效应，空心板的内力计算，以及验算在不同条件下的空心板配筋。再依据河道情况以及上部结构计算结果。设计桥梁的墩柱和桩基，计算盖板内力及配筋，以及墩柱和桩的大小和高度，以及墩柱和桩的配筋计算。50953
整个设计从上部结构的板设计到支座设计，到下部结构的墩柱和桩基设计，都进行了详细的设计和计算。

Abstract With the social and economic development, Bridge engineering to develop rapidly, Design and construction techniques have been greatly improved.
The design of the bridge is a bridge on the main roads of Zhang Jia Gang City,the bridge across the river,no shipping requirements.Apply the theoretical knowledge to design bridges,through the computer plot.
This design has a great inspiration for me,design a bridge from reality,you must be investigated,learn designed,compare the different bridge,finally the most reasonable option.According to the actual situation,different traffic,different needs,to select the best design,the selection of Hollow Slab Bridge,belonging to small and medium bridges.The design,hollow section properties are calculated,as well as the role of hollow effect,hollow internal force calculation ,and checking under different conditions of hollow slab reinforcement.and then based on the river as well as the upper structure calculations,design bridge piers and pile, calculate internal forces and cap beam reinforcement ,and the pier and the size and height of the pile ,and piers and piles of reinforcement calculation.
The whole design of the plate from the upper structure design to support the design, to the pier and pile substructure design, have carried out a detailed design and calculation.
Keywords: Bridges ,Prestressed concrete structure, The internal force, The calculation of reinforcement.
