Based on the ground treatment project of Zhuhai Offshore Engineering Building Base of China National Offshore Oil Corp marine engineering module final assembly site，and according to the engineering characteristics of heavy load and geologic condition of great fluctuation of the upper overburden，we design the soil consolidation schemes by dynamic replacement method and dynamic consolidation drainage method respectively in subregional ground，compare the ramming volume，excess pore water pressure and ground strength，obtain the dissipation rate of the excess pore water pressure and soil consolidation effect of different consolidation schemes，and verify the design parameters such as the ramming energy and interval time，so as to provide a basis for the large-area ground treatment and serve as reference for the popularization of the dynamic consolidation method in the soft soil foundation treatment .
