关于城市高架桥维修加固方案的研究

The study of urban viaduct repair and reinforcement

由于原设计荷载标准偏低,施工管理的粗放等原因,使得高架桥在当前运营过程中出现较多的病害,难以满足日益增加的使用要求,须进行必要的维修加固。以城市高架桥的维修加固设计为例,详细讨论了城市高架桥的病害特点、维修与加固方法等。

Because of the low standards of the original design load,the extensive construction management and other reasons,make the bridges difficult to meet the increasing requirements and the diseases occur more frequently,in that case,repair and reinforcement going to be necessary.This project use a city viaduct repair and reinforcement design as a example,discussed in detail the characteristics of urban viaduct's diseases,the repair and reinforcement methods.
