| Abstract: | New materials and technology for constructing embankments with soilbags are studied and developed,in which vast excavated soils and hydraulic fill clayey soils with high water content are fully used in place of the conventional rockfill materials.New protective materials for the embankments with soilbags are also developed by use of dredged marine sand,low temperature clinker cement and a combined superplasticizer consisting of copolymer and condensate type water reducers.The engineering properties of the soilbags and the protective materials are analyzed through experiments,and the corresponding construction technology is developed so as to solve the technical problem of shortage of rockfill materials in the coastal development and to protect the environment in coastal areas. |
