中文摘要：

以连云港30万吨级航道建设工程为依托,对以疏浚淤泥为充填材料的充填泥袋筑堤的关键技术问题进行了离心模型试验研究.试验的结果表明：（1）充填泥袋的沉降主要发生在施工期,竣工后变化很小,从沉降安全上考虑,黏粒含量不宜大于22％;（2）泥袋的沉降随黏粒含量的增加而增大,不排水强度随黏粒含量的增加而减小;（3）泥袋堤体的沉降在堤体范围内呈现中间大两边小的分布,在筑堤的过程中,堤身发生比较大的压缩;（4）泥袋堤体失稳时,变形主要表现为沉降,水平变形较小,表现为圆弧滑动破坏型式.

英文摘要：

Based on the waterway engineering of three hundred thousand tons in Lianyungang harbor,centrifuge modeling test are used to study the key technology of embankment with filled soil bags.The Results of centrifuge modeling test show that：（1） The settlement of the embankment mainly happened in construction but very small after completion,considering the security of settlement,the clay content of filled soil should be controlled under 22％ ;（2）As clay content of filled soil increases,the settlement increases but the undrained shear strength of filled soil decrease; （3） The settlement of the embankment is large in the center but small at both sides,the compression of the embankment is large; （4） When the embankment failed,the settlement is primary but horizontal deformation is small,the failure model of embankment is circular sliding.
