| Abstract: | The article discusses the advantages and disadvantages of various treatment methods of the old and new bridge joints when the existing bridges are widened.Based on the cases of bridge widening,the article gives the conclusion on the master treatment principle of the old and new bridges before the bridge widening,and the selection of connection time,and also outs forward several problems required to consider in the superstructure treatment of bridge widening,which is certainly valuable for the widening reconstruction of the existing bridges. |
