摘要
文章对江六高速公路扬州南绕城段拼宽桥梁在施工中主要存在的问题,平面、高程控制原则,病害处理的动态设计进行介绍,建议在设计外业调查阶段对老桥的尺寸进行现场调查与复核,并测量关键点坐标及高程;后期施工中需根据设计调整的情况进行动态设计。
This paper introduces the existing problems, plane control principle, elevation control principle and dynamic design of disease treatment of South Yangzhou section of Jiangtiu expressway. It is suggested that the size of the old bridge should be investigated in field investigation stage,coordinates and elevation of key points should be measured. Dynaminc design should be conducted in latter period of construction according to design adjustment.
