| 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,给出了等应变条件下碎石桩复合地基中超孔隙水压力长消的简化解析解;结合几种实用的动孔压增长计算模型,给出了简化解析解的具体表达式。

| Abstract: | The actual deformation of composite foundation of gravel piles is simplified as equal strain condition.Aimed at single permeable boundary condition,the increasing ratio of dynamic pore pressure as force source is expressed as the function of depth z and time t,the simplified analytic solution of generation and dissipation of the excess pore water pressure in composite foundation of gravel piles is derived under equal strain condition.Based on some calculation models of dynamic pore pressure,the specific expressions of simplified analytic solution are given. |
