摘　　要：汉江雅口航运枢纽工程一期围堰原设计存在工程量大、工期紧、材料供应难、施工效率低、护坡不能满足要求等问题,通过研究类似围堰工程的施工技术,结合该工程的实际情况,采用充填沙袋戗堤、粉细沙堰体、充填沙袋及模袋混凝土护坡的土石围堰结构,成功解决了原设计中存在的问题,顺利地在节点工期内高质量地完成了工程施工。There are some problems in the original design of the first-phase cofferdam of Yakou shipping hub project of the Han River,such as large engineering amount,short construction period,difficult material supply,low construction efficiency and unsatisfactory slope protection.According to the actual situation of the project,the earth and rock cofferdam structure with sandbag-filled berm,silty sand weir,sandbag-filled and mold bag concrete slope protection has successfully solved the problems existing in the original design,and completed the project construction in high quality within the nodal duration.
