In view of the fact that there is relatively little research on soil squeezing effe ct of conical-perforated column composite pipe pile, the lateral displacement and surfa ce uplift of conical-perforated column composite pipe pile after single pile is pressed i nto soil are observed by static pressure pile sinking method, and the change law of soil lateral displacement and surface uplift during pile sinking is analyzed. It is found that the lateral displacement increases with the increase of pipe pile driving depth, and whe n the pipe pile is fully penetrated, the soil lateral displacement ends, and the influence range of soil lateral displacement is 2 days.
