摘　　要：新旧混凝土接茬在很多结构中都存在,但有防水要求的混凝土结构相对不易处理,以郑徐客运专线兰考南站为例总结阐述旅客地道及中小桥涵变更接长中新旧混凝土接口处的防水工艺。The new and old concrete picking exists in many structures, but the concrete structure with waterproof requirements is relatively difficult to deal with. In this paper, taking Zhengzhou-Xuzhou High-speed Railway Lankao South Railway Station as an example, the paper expounds the changes ofthe length ofmiddle and small bridges, waterproofing technology of interface between new and old concrete.
