为研究有孔管桩静压沉桩效应,基于圆孔扩张理论,推导出有孔管桩静压沉桩产生的超孔隙水压力、塑性区半径等解析表达式。同时根据土压力理论,推导出超孔隙水压力与上覆有效压力关系的表达式。最后结合工程案例,比较分析静压无孔管桩和有孔管桩超孔隙水压力的变化情况,揭示出有孔管桩静压沉桩产生的超孔隙水压力变化规律,验证了有孔管桩能够加速超孔隙水压力的消散,并降低超孔隙水压力最大值。

英文摘要：

In order to study the sinking-pile effect of the pipe-pile with holes,the analytic solution of the excess pore water pressure and the radius of plastic zone were deduced during the static sinking pipe-pile with holes on the base of cylindrical cavity expansion theory. According to earth pressure theory,the expression between excess pore water pressure and overlying effective stress were also derived. Finally,the varieties of excess pore water pressure were contrastively analyzed between pipe-pile without hole and pipe-pile with holes during static sinking-pile by combining with engineering cases. The change regulation of excess pore water pressure was revealed during the static sinking pipe-pile with holes. The research results showed that the pipe-pile with holes could accelerate the dissipation of the excess pore water pressure during static sinking pile,and reduced the maximum of excess pore water pressure.
