The bucket-based structure is successfully applied to the breakwater construction.In order to discuss the possibility of this structure to be applied in wider construction field,we analyze the data of unilateral riprap loading monitoring to the east breakwater project in Xuwei,Lianyungan Port,conclude the horizontal movements,rotary motions,internal forces,surrounding soil pressures and soil parameter variation regularity of bucket-based structure under unilateral riprap loading condition,and validate that the bucket-based structure can be applied and popularized in port structures which mainly bear horizontal forces such as revetment and cofferdam.
