Abstract According to some typical field tests，the validity of soil properties and drainage condition for saturated soft soil foundation by dynamic consolidation method are studied. The treatment techniques of the method are discussed，which include the development and dissipation of pore water pressure，single point tamping energy，compacting number，the time between tamping and the next tamping，and the affecting scopes，etc. The result shows that the drainage conditions，for various saturated soils，are different from each other. In practical engineering，design parameters and the bearing capacity of reinforced grounds are determined by soil properties. In a certain depth of soil layer，the pore water pressure induced by impact loading is usually higher than its self-weight stress and then produces many fissure channels，which accelerates the drainage process. For the ground soil with low permeability，drainage measurement and small dynamic loading are should be adopted，but for the ground soil with higher permeability，a greater dynamic loading should be adopted.

Key words： soil mechanics dynamic consolidation method saturated soil foundation treatment process parameters
