摘要
20世纪60～70年代修建的桥梁由于设计荷载标准较低、桥梁结构强度不足、桥面宽度不足等原因严重制约着当地经济的发展。随着交通运输量的增加,车辆超重、超载现象越来越严重,已危及到旧桥的行车安全,故对旧桥进行维修加固迫在眉睫。
The bridges built in 1960s or 1970s have some problems such as the design load standard is rather low, structure intensity is insufficient, width of bridge pavement is insufficient and so on, so the development of local economy has been restricted terribly. Along with the increase of traffic, the phenomenon of overweight and overfreight are more and more severe, which has endangered the security of traveling on old bridges, so maintenance and reinforcement of old bridges is urgent.
