摘　　要：先简支后连续空心板梁桥梁板安装就位后,接下来的湿接头施工是桥梁简支变连续最重要的一道工序。砂箱法湿接头连接工艺具有施工便捷、混凝土外观良好、支护结构易清理、支座及盖梁保持整洁不易被污染等优点。论文以某工程为例,对先简后连空心板梁桥湿接头砂箱法施工工艺展开讨论,以便为类似工程提供参考。After the installation of the first simply supported and then continuous hollow plate beam bridge plate,the following wet joint construction is the most important process of the transition of simple supported beam to continuous beam bridge.Sand box method wet joint connection technology has the advantages of convenient construction,good concrete appearance,easy to clean the supporting structure,support and cover beam to keep clean and not easy to be polluted.Taking a project as an example,the paper discusses the construction technology of wet joint sand box method for the bBridge with first simply supported then continuous hollow plate beam,so as to provide reference for similar projects.
