摘　　要：地下连续墙结构是目前基坑工程的一种较成熟的支护、排水一体化结构。文章结合汕头市中阳隧道基坑施工的具体情况,研究了超深地下连续墙成槽施工技术在护堤海岸城市复杂地基中的应用情况,通过配制高分子聚合物泥浆,解决了复杂软弱地质易塌孔的问题,通过引入超声波装置和新型清孔装置,保证了地下连续墙成槽和成型质量,提高了施工效率,创造了经济收益,为后续基坑工程施工提供了有利条件。Underground continuous wall structure is a mature integrated support and drainage structure in foundation pit engineering at present.Based on the specific situation of foundation pit construction of Zhongyang Tunnel in Shantou City,this paper studies the application of ultradeep underground continuous wall trenching construction technology in the complex foundation of coastal cities with embankment protection.By preparing high polymer slurry,the problem of hole collapse in complex weak geology is solved.By introducing ultrasonic device and new hole cleaning device,the trenching and shape forming quality of underground continuous wall are ensured,the construction efficiency is improved,and the economic benefits are created,providing favorable conditions for subsequent foundation pit construction.
