摘要
城市道路改造过程中,对路面的加宽主要集中在桥梁、路基部分。为确保公路工程的顺利实施,提高公路工程的施工质量,需对其进行科学的拼宽加固设计,选择合理的加固方案,具体内容包括:新增钢筋混凝土悬臂梁、单边新桥、新增边拱、增加主梁和拱肋等。以实际工程为例,分析了城市桥梁拼宽加固设计原则,并对城市桥梁拼宽加固设计方法进行了探讨。
In process of urban road reconstruction,widening of pavement is mainly concentrated in bridge and subgrade.In order to ensure smooth implementation of highway engineering and improve construction quality of highway engineering,it is necessary to carry out scientific widening and reinforcement design,and select reasonable reinforcement scheme.The specific contents include:new reinforced concrete cantilever beam,new unilateral bridge,new side arch,increasing main beam and arch rib,etc.Taking the actual project as an example,the design principles of widening and strengthening of urban bridges are analyzed,and the design methods of widening and strengthening of urban bridges are probed.
