This graduation design is the design of Dongshan head bridge of the 111 line of national road. Through the understanding of the local geological conditions and the learning of the knowledge of the bridge in the four years of the University, three specific alternatives are determined. They are prestressed concrete continuous girder bridges, reinforced concrete simply supported beam bridges and arch bridges respectively. Considering the effect of the force, hydrology, geological structure and earthquake and temperature influence of the beam, it is determined that the bridge substructure should follow the safety and durability, meet the requirements of the use, at the same time, the cost is low, the maintenance and maintenance are convenient, and the surrounding landscape should be coordinated. The final choice is a reinforced concrete simply supported beam bridge, which is 100m in length and divided into 5 spans, with a span of 20m. According to the design data and design examples, the size is preliminarily drawn up, and the cross section design, reinforcement and checking calculation, the calculation of the lane plate, the crack width and deflection checking under the normal limit state of the permanent condition are calculated respectively. At the same time, design and check with reference to relevant codes and regulations, so as to achieve the desired design requirements of the bridge. Key words: reinforced concrete; simply supported bridge; bridge
