【摘要】 将碎石桩复合地基的实际变形简化成等应变情况,针对单面透水边界条件,将作为力源项的动孔压增长率表达成为深度z与时间t的函数,利用分离变量法和Green函数,给出了等应变条件下考虑井阻的碎石桩复合地基中超孔隙水压力长消的简化解析解。更多还原

【Abstract】 The actual deform of stone columns composite foundation was simplified equal strain condition.Based on single permeable boundary condition,the dynamic pore press-increasing ration as force source was expressed as the function of depth z and time t,using separation of variables and green function,the simplified analytic solution of generation and dissipation of excess pore water pressure in stone columns composite foundation was developed under equal strain condition and considering well resistance.更多还原
