Based on the fundamental principles of soil plastic mechanics
the formulas calculating the squeezing stress in the expansion of cylindrical cavity during pile-driving are deduced taking the soil structural damage into account. The three-dimensional distributions of the squeezing stress and the terminal expansion force during pile-driving are analyzed. So the shortcoming of the classical cylindrical cavity expansion theory can be overcome. The mechanism of soil squeezing during pile-driving will be revealed more clearly. Finally
the pore pressure due to pile-driving is discussed based on Henkel’s equation.
