Abstract: This paper elucidates the current statution and development trend of treatment technique of soft soil foundation in China, and points out the conditions of application and effect of treatment techniques for various soft soil foundation. It foucs on analyzing the characteristics and feasible treatment methods of hydraulic fill on filled recently, then more ever presents suggest that the method of preloading dynamic statics consolidation is mainly direction of treatment technique of soft soil, and Preloading dynamic consolidation make the filling reach ultra concretion lamella,it makes important engineering significance.
