【摘要】 设计强夯试验 ,动态观测了超静孔隙水压力的变化。考虑深度、单点总夯击能、夯击遍数、累加平均夯击能、渗透性和时间等因素对超静孔隙水压力变化的影响 ,利用回归分析 ,提出了强夯孔隙水压力数学模型 ,用此模型可以确定强夯施工时的夯间时间间隔。

【Abstract】 In an engineering case,dynamic consolidation test was designed ,and excess pore water pressure test was carried out. Considering for the depth, tamping energy in single point, tamping rounds, soil permeability, etc., which affect the variation of excess pore water pressure, numerical model for pore water pressure in dynamic tamping was constructed by regression analysis. The model can be applied to determine the interval between two tamping rounds.
