| Abstract: | DJM is a soil improvement technology which pneumatically delivers powdered reagent into ground and mixes it with soils to form a soil-reagent column.It is an efficient method for reinforcement of a soft foundation.Bearing capacity of the dry jet mixed piles is an important parameter for the composite foundation,which is difficulty to determine because of the complexity between the pile and soil.In this paper authors compare different methods,and suggest guidelines for using different methods in determination of bearing capacity. |
