| Abstract: | The process of pile pressing of static pressure pile is simulated as expansion of round hole. Based on expansion of round hole in plastic mechanics of soil, a formula for estimation of influencing sphere of plastic area and expansion pressure during pile pressing and a formula for horizontal and vertical displacements of soil body during pile pressing were suggested. |
