Study on the Rapid Treatment Technology of Silty-fine Sand Foundation of Coastal Highway

The problems of Silty-fine sand foundation of coastal highway are analyzed. On this basis,considering the environmental characteristics of coastal area and characteristics of the existing foundation treatment methods,impaction and grind method( IGM) and vibration compaction method as the rapid treatment technology of Silty-fine sand foundation of coastal highway is first proposed. The field experiment result proves the feasibility of these two methods.
