摘　　要：在胜利油田孤东海堤堤前滩地的保滩促淤工程中,目前普遍使用的丁坝结构形式,要么容易被破坏,要么造价高昂、施工难度极大,为此,我们引入了新型双排管桩丁坝。双排管桩丁坝是以管桩技术为基础的一种新型丁坝结构形式,详细介绍了它的结构,以及在保滩促淤工程中的实施过程,并对其优、缺点进行了分析比较,指出了它的改进方向和应用前景。T-shaped dams are often built in the engineering for shore protection and fa- vourable deposition in front of Gudong Dam at Shengli Oil Field. They are expensive, easy to be destructed, and difficult to be constructed. Therefore, a new type of T- shaped dam with piles of double tube-rows are built by means of the techneque using concrete tube piles. The dam structures and the procedure of its construction for shore protection and favourable deposition are introduced in details. Also its advantages and disadvan-tages are analysed. Its improvement posibility and application prospects are presented finally.
