摘　　要：民航建工深排工程海上现浇结构施工工艺非常具有代表性。集中反映出海上现浇结构施工受环境因素影响多、流水作业组织要求高等特点。文章通过介绍深排工程海上结构施工关键工艺,重点在于协调解决浅海工程施工受潮汐影响大、作业面狭窄、协调难度大等问题。体现了在有限条件下现浇结构施工技术、质量控制、组织协调措施。解决一些浅海作业条件下现浇结构面临的模板支撑体系设计、赶潮施工安排、工序交叉协调问题。对后续海上施工具备一定借鉴意义。The construction technology for offshore cast-in-place structure is typical in CAAC deep drainage works.It reflects that the construction of offshore cast-in-place structure is mainly affected by environmental factors and requires better organization of flow process.Based on the introduction to the key construction technology of offshore structure in deep drainage works,the solution to some problems existing in shallow sea construction are focused on,including tidal effect,narrow operation surface and the difficulty in coordinating,complete with the construction technology,quality control,organization and coordination measures adopted for cast-in-place structure under limited conditions.The design of formwork support system,tide-riding construction arrangement and the issues around procedure clashes shall be improved to assist the construction of the cast-in-place structure within the range of shallow sea,which has certain reference for the subsequent offshore construction.
