某工程水下地形复杂，涨落潮流速大、水流动力作用强，致使工程深水段围堤施工遇到很大困难。为确保顺利实现工程目标，结合施工条件，提出了深水段袋装砂围堤对拉船施工、快速建立水上作业平台、控制平均过水线等施工方法，有效解决了传统施工过程中出现的袋体漂移、翻卷、扭曲、撕裂等技术难题，加快了水下围堤工程的施工进度，保证了工程质量和工程安全。施工方法可为同类工程借鉴。

The construction of deep underwater cofferdam of a project is difficult because of complicated underwater terrain, large tide-flow velocity and the strong hydrodynamic force. In order to realize the project objective smoothly, in consideration with the construction condition, the construction methods are proposed such as opposite-pull ships construction for sand-bag cofferdam in deep water, fast establishment of water operation platform, control of the average overflow line. By these measures, the technical difficulties, including drift, rolling, distortion and tearing of the bags, were solved, the construction progress of the underwater cofferdam was accelerated, and engineering quality and safety were ensured.
