公路工程路桥过渡段施工技术

Construction Technology of Road-Bridge Transition Section in Highway Project

路桥过渡段桥梁刚性桥台与柔性路堤两种结构物的刚度差异较大,由于设计不合理、施工工艺控制不到位等原因,导致运营期常出现桥头跳车现象,影响行车安全,且处置难度大,成本高。通过对路桥过渡段不均匀沉降产生跳车原因进行分析,有针对性的采取应对措施,可以有效的防治桥头跳车,达到降低运营期养护成本,保障行车安全的目的。

The stiffness difference between rigid bridge abutment and flexible embankment in bridge transition section is quite large.Due to unreasonable design and inadequate control of construction process,bridge head jumping often occurs during operation period,which affects driving safety and is difficult to handle and costly.By analyzing the causes of vehicle jump caused by uneven settlement of road-bridge transition section and taking corresponding measures,the bridge jump can be effectively prevented and controlled,the maintenance cost during operation period can be reduced and the driving safety can be guaranteed.
