Abstract: Soil-mixing piles are widely used in practical engineering, such as the retaining and protection of foundation excavation, reinforcement of soil, etc. A brief introduction on the development history of soil-mixing method was given, the existed researches on the performance of soil-mixing piles were analyzed. It includes the interaction between soil-cement pile socket and reinforce inner steel pile, the bending and pulling resistance of the soil-cement piles and the transmission of loads. In addition, a new type of soil-mixing pile is also mentioned. Besides, the current problems on related studies are listed with a prospect of its future development.

Keywords: soil-mixing pile; interaction; flexural performance; structure optimization
