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。 In order to study the effect of static pressure pile with perforated pipe pile, the analytical expression of excess pore water pressure and plastic zone radius induced by static pressure pile with perforated pipe pile is deduced based on the theory of circular hole expansion. At the same time, according to the theory of earth pressure, the relation between excess pore water pressure and overburden effective pressure is deduced. Finally, with the engineering case, the variation of the excess pore water pressure of the static pressure non-porous pipe pile and the perforated pipe pile is analyzed and compared. The variation of the excess pore water pressure produced by the static pressure pile with the perforated pipe pile is revealed. Piles can accelerate the dissipation of excess pore water pressure and reduce the maximum pore water pressure.
