摘　　要：为保证某漫水桥的正常通行,在考虑施工现场条件的基础上,设计了一种施工便道用漫水桥结构。介绍该漫水桥的结构设计,对其结构安全进行检算,并从桥位、桥面高程、桥型、桥台和行车道等方面总结设计思路。结果表明,该施工便道用漫水桥结构设计总体上安全可靠,将该漫水桥应用于现场施工,使用期间漫水桥结构稳定,效果良好。In order to ensure the normal traffic of an overflow bridge,an overwater bridge structure for construction road is designed on the basis of considering the construction site conditions.This paper introduces the structural design of this overwater bridge,checks its structural safety,and summarizes the design ideas from the aspects of bridge location,bridge deck elevation,bridge type,abutment and lane.The results show that the structure design of the overwater bridge used in the construction road is generally safe and reliable.This kind of overwater bridge is applied in the field construction,and the structure of the overwater bridge is stable and its effect is good during its use.
