Abstract: Cement mixing pile reinforcement technology is one of the most commonly used and effective methods for coastal soft soil foundation treatment. Fully grasping the dynamic characteristics and dynamic evolution laws of cement solidified coastal soft soil is an important prerequisite to ensure the safety and stability of cement mixed pile soft soil foundation under the dynamic loads generated by dense subway network and continuous wave action. A review is conducted on the dynamic characteristics and constitutive models of cement solidified coastal soft soil both domestically and internationally. The dynamic test types, dynamic characteristic indicators, dynamic constitutive models, and optimization methods of cement solidified coastal soft soil are systematically summarized and analyzed. The shortcomings of current researches on the dynamic characteristics of cement solidified coastal soft soil are discussed, and targeted research suggestions are explored, which may provide new thinking and ideas for the study of the dynamic characteristics of cement soil.

Key words: soil dynamics, cement stabilized soil, dynamic load, dynamic strength, dynamic characteristics
