The Experimental Research on the Bag-Grouting-Pile Composite Foundation in Coastal Soft Foundation Treatment

As a new ground treatment technology, the bag-grouting-pile composite foundation is used in railway soft soil reinforcement. In this paper, the application effect of bag-grouting-pile in coastal soft foundation treatment was studied in this experimental research; the deep settlement and the deep horizontal displacement of embankment edge in bag-grouting-pile composite foundation are tested in the research. The results of research show that the bag-grouting-pile composite foundation is a cost-effective ground treatment technology using in coastal soft foundation treatment.
