致远桥施工图设计
摘 要
本次毕业设计实现了对预应力混凝土简支T型梁桥的设计，本文通过对国内外相关文献的翻译、整理与总结，表达出我对预应力混凝土简支T形梁桥的一些认识。相比于普通混凝土梁桥，预应力混凝土梁桥能够预先在结构体系内产生预压应力，且能够使用高强材料，大大减少了钢筋需求量，进而减轻了自重，降低运输成本；本设计采用简支体系，因而采取的是静定体系，因此需要的地基等级也相对较低，进而减小了施工成本。因此，混凝土简支梁桥设计有一定的技术经济指标优势，广泛使用于我国公路和中小跨径桥梁建设中。

Construction Design of Zhiyuan Bridge
Abstract
Abstract：This graduation project carries out a design of prestressed concrete free T-beam bridge. This paper summarizes my understanding of prestressed concrete free T-beam bridge by reviewing and collating relevant literature at home and abroad. Compared with ordinary concrete girder Bridges, prestressed concrete girder Bridges can generate prestress in the structural system. It can take use of high-strength materials, which greatly reduces the demand for reinforcement, thus reducing the dead weight and reducing the transportation cost. This design adopts simple support system, whose statically determinate structure puts low requirements on the basis, thus reducing construction cost. Therefore, the concrete simply supported beam bridge has many advantages and is widely used in the construction of small and medium span Bridges in China.
