S103郑新线刘彦庄桥断板更换方案

S103 Zhengxinxian Liuyanzhuang's Bridge Breaks Board Replacement Plan

针对公路养护工程中桥梁维修和行车道板的更换,通过对行车道板通用图的定性分析和改造,使用桥梁博士建立力学模型,从而验算结构安全性,估算结构配筋与改造板配筋对比,在时间紧的情况下,使改造后的行车道板满足结构受力需要,经实践检验,该方法可行,为养护工程中的桥梁维修及行车道板的更换提供借鉴。

In view of the highway maintenance project in the bridge service and the lane board＇s replacement,through to the lane board general chart＇s qualitative analysis and the transformation,use bridge doctor establishes the mechanical model checking calculation safety of structure,the estimate structure reinforcing bars and the transformation board reinforcing bars contrast,in the time tight situation,after causing the transformation the lane board meets the structure stress needs,after the practice examination,this method is feasible,provides certain model to the later maintenance project＇s bridge service and the lane board＇s replacement.
