The first step is to give three types of the bridge according to topograohic consider the outward appearance,easy of construction,cost and other aspects to choose the best program for this last,ing up with the best program for the design with the full bridge 130m,divided into 5 cross ,each cross26m and the designed load for the highway isⅡ . This design includes the following aspects: draft of prestressed concrete box girde section size, the calculation of crosssection properties and internal forces,the assignment and intensity check of reinforced in the grider, the estimation of prestressing loss and the assigiment of reinforced in the grider of carriageway and the setting of affiliatied facilities etc. The calculation method includes lever,eccentricpressed method and other calculation methods and it refers to the provisions of relevant standards to design and check. This design solve the problems in the design of calculation and checking and draw the corresponding engineering the project budget documents and arrangement and method for construction according to the design materials,survey and geological materials,engineering drawings and field conditions.
