摘　　要：针对淤泥软基上筑抛石斜坡堤稳定性差的问题,采用通长砂袋基础的方法,通过土工织物的加筋作用提高了抛石斜坡堤整体稳定性,同时缩小了抛石斜坡堤断面,节省了造价。以宁波大榭招商国际集装箱码头陆域形成工程为例,介绍通长砂袋基础抛石斜坡堤在淤泥软基筑堤工程中的设计方法、特点及在本工程应用时相对于传统斜坡堤的技术经济优势。In view of the problem of low stability of constructing the rubble-mound dike on soft silty subsoils,using long sand-filled bags,the whole stability of the rubble-mound dike increases through the reinforcement effect of geotextiles,in the same time the section area of the rubble-mound dike is reduced and the cost is saved.Taking the land formation works for Ningbo Daxie China Merchants International Container Terminal as a study case,this paper not only introduces the design methodology and characteristics in respect of the long sand-filled bags&rubble-mound dike structure on soft silty subsoils,but also describes its technical and economic advantages comparing with the conventional slope dike.
