This article summarizes the result of design, detect and reinforce of CFS( concrete-flash-steel slag)pile composite foundation, particularly analyzes and illustrates the characteristics and mutual relation of bearing capacity characteristics, additional stress, stress distribution ratio between pile and soil and load distribution ratio of CFS pile composite foundation. Simple comparison is done between the CFS pile composite ground and the similar CFG pile composite ground.
Keywords: replacement ratio; bearing capacity; composite foundation; stress distribution ratio; pile and soil; load  distribution; ratio
