摘要: 饱和软粘土地基沉桩过程中桩土挤压所引起的桩周土体超孔隙水压力效应是非常显著的.本文从弹塑性理论出发推导出沉桩过程中桩周土体挤压应力及超孔隙水压力的计算公式,给出了考虑挤压应力和超孔隙水压力等影响因素的合理打桩间距的确定方法

关键词: 饱和软粘土, 挤压应力, 扰动, 孔隙水压力, 打桩间距

Abstract: The excess pore water pressure of saturated soft clay foundation caused by pile pushing is obvious.The method for calculating squeezing stress and excess pore pressure by elastic-plastic theory is deduced in this paper,and furthermore,the reasonable pile spacing by regarding the influence of both squeezing stress and excess water pressure is given.

Key words: saturated soft clay, squeezing stress, disturbance, pore pressure, pile spacing
