道路桥梁出现沉降,对在引道路堤以及桥台间造成危害非常大。即便出现沉降的差异不大,也会造成桥头出现跳车等现象,给行车带来较大的安全危害。本文主要探讨道路桥梁沉降段的路基路面沉降机理,以及对施工中的控制等问题。 Subsidence of roads and bridges has caused great harm to the road embankments and abutments. Even if there is little difference in settlement, it will also cause the phenomenon of jumping at the bridgehead and bring about greater safety hazards to the driving. This paper mainly discusses the subsidence mechanism of subgrade and subgrade in the settlement section of road and bridge as well as the problems in the construction control.
