摘　　要：旧桥拓宽设计要考虑旧桥状况 ,用发展的眼光确定拓宽部分的设计标准 ,还应注意新旧梁的联结处理及新旧墩台的关系。When doing the designs for widening of old bridges,we should consider the situations of old bridges. We should determine the design standard for the widening parts in a long-term light and be careful of the link treatment of the new and old beams and the relationships between the new and old abutments.
