海堤工程常用的结构型式比较单纯,如本市的围海造地工程中的围堤和长江口整治工程中设计的导堤建筑物都是土石斜坡堤结构。据国内外有关文献资料介绍,抛石斜坡堤用于港口工程的防波堤和围垦工程的围堤,是一种比较安全可靠的结构,然而本市无石料产地,所以近几年本市建成和在建的海堤工程都采用编织袋充泥代替部分抛石,然而编织袋充泥结构在深水下施工比较困难,若作为独立的建筑物会令人担心,例如在《长江口深水航道治理工程(一期)工程可行性研究
The commonly used structure types of seawall engineering are quite simple. For example, the embankment in the reclamation project of the city and the embankment structure designed in the regulation of the Yangtze Estuary are all the earth-rock slope structures. According to the domestic and foreign literature, the sloping slope embankment for the port works and the reclamation of the breakwater embankment, is a relatively safe and reliable structure, but the city without stone origin, so in recent years the city completed and in The construction of the seawall works are woven bag filled with mud instead of part of the riprap, but the bag filled with mud structure construction in the deep water is more difficult, as a separate building will be worrying, for example, "the Yangtze River Estuary Waterway Control Project Phase I) Engineering Feasibility Study
