摘　　要：在进行桥梁的细部设计时,需要考虑的事情有很多,如对多个桥梁的结构设计进行分析,选择好施工所需要的材料,尤其是对混凝土材料的种类和性能等情况一定要分析好。在很多公路中设计了简支板梁桥,但是由于各种因素导致其发生病害,必须对其进行维修加固,主要措施有重新进行桥面铺装,修复已破损的结构,对新旧混凝土连接面进行凿毛处理,对于结构损坏严重的要进行重新浇筑。In the detailed design of the bridge, there are many things to consider, such as the structural design of multiple bridge analysis, choose construction materials needed, especially on the types and properties of concrete material analysis must be good.In many highway design of simply supported plate girder bridge, but due to various factors lead to the occurrence of disease, it must be strengthened, the main measures to repair damaged pavement structure, the connection between new and old concrete surface roughening treatment, the structure of the serious damage to re pouring.
