此次设计是对镇平县滴水崖桥升级改造，桥位于二龙乡白湾村南，对其进行工程升级改造，将原技术标准由三级公路提升为二级公路，设计速度为80公里每小时。桥面宽度（1.5m人行道+11.4m行车道+1.5m），桥梁设计全长8m，桥梁计算跨径为4m。主梁截面为预制T型梁，采用钢筋混凝土结构。设计时首先跟据地形地貌拟定方案，然后进行方案比选确定设计方案。再依次进行桥梁的平面设计，桥梁的纵断面设计，桥梁上部结构设计，支座设计。最后进行施工图绘制。

This design is to upgrade and reconstruct the Dishuiya Bridge in Zhenping County, which is located in the south of Baiwan Village, Erlong Township. The project will upgrade and reconstruct it, and upgrade the original technical standard from third-class highway to second-class highway, with a design speed of 80 kilometers per hour. The width of the bridge deck (1.5m sidewalk+11.4m carriageway+1.5m), the designed total length of the bridge is 8m, and the calculated span of the bridge is 4m. The main beam section is prefabricated T-beam, which is of reinforced concrete structure. When designing, the first step is to develop a plan based on the terrain and topography, and then compare and select the design plan to determine it. Then proceed with the plane design of the bridge, the vertical section design of the bridge, the upper structure design of the bridge, and the support design in sequence. Finally, draw the construction drawings.

The bridge deck width (1.5m sidewalk +11.4m carriageway +1.5m), the designed total length of the bridge is 8m, and the calculated span of the bridge is 4m. The cross section of the main girder is a precast T-beam, which adopts reinforced concrete structure. When designing, firstly, draw up the scheme according to the topography, and then compare and select the schemes to determine the design scheme. Then the plane design of the bridge, the longitudinal section design of the bridge, the superstructure design of the bridge and the bearing design are carried out in turn. Finally, draw the construction drawing.
