One of the technical difficultiesin structures design is to choose the structural type in order to achieve the project goal on the muddy coast.The bucket-based structure can avoid technical difficulties of maritime soft handle,and is a new structure suitable for the silt coast.This paper describes the structure selection of the new bucket-based structure in the application,checking method of structural stability,structural design method,and engineering applications,etc.It is available for reference when the bucket-based structure is applied to similar engineering.
