摘要
本文将静压桩的压桩过程模拟为园孔扩张课题，根据土塑性力学园孔扩张理论分析提出了压桩时塑性区影响范围和扩张压力的估算公式。
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.
