摘　　要：某沿海地区软土基础外海土石围堰施工期间,局部围堰在遭遇大潮汛时出现沉陷滑移险情,并伴随贯穿裂缝。本文分析外海围堰出现沉陷滑移的原因,结合工程实际现状,从加快建设工期、有效控制投资等角度出发,调整围堰设计结构断面型式,较好保障项目推进,可为其他类似工程提供借鉴经验。During the construction of offshore soil and rock cofferdam on soft soil foundation in a coastal area,local cofferdams encountered the danger of sinking and sliding during high tide floods,accompanied by cracks that penetrated through them.The paper analyzes the reasons for the settlement and sliding of offshore cofferdams,and based on the actual situation of the project,adjusts the design structure and section type of the cofferdam from the perspectives of accelerating construction period and effectively controlling investment,which can better ensure the progress of the project and provide reference experience for other similar projects.
