STUDY ON THE RECONSTRUCTION OF OVERPASS BRIDGE WITH LIMITED CLEARANCE IN EXPRESSWAY RECONSTRUCTION AND EXPANSION
The reconstruction plan of overpass bridge is an important component of expressway reconstruction and expansion design.Due to the problem of historical omission,there will be special construction work points of overpass bridge with limited bridge location and limited clearance under bridge,which is one of the difficulties in expressway reconstruction and expansion design.Taking a special reconstructed bridge with fixed bridge position and limited clearance under the G0512 Chengdu-Leshan expressway,which will be expanded and opened to traffic in 2022,as an example,this study discusses the design process of the reconstructed bridge in detail,in order to provide reference for similar projects.
