作者介绍了:在施打钢管桩时,测试周围土体中超孔隙水压力的分布情况。并应用小孔扩张理论,分析打桩瞬间土体中总应力和超孔隙水压力的变化规律,从而导出了弹、塑和水裂破坏区的范围,由此分析打桩对附近连续墙成槽的影响。
The author describes the distribution of excess pore water pressure in the surrounding soil when testing steel pipe piles. The theory of pinhole expansion was used to analyze the variation law of total stress and excess pore water pressure in the soil immediately after pile driving so as to derive the range of the elastic, .
