| 摘 要： | 根据流固动力耦合方法分析强夯加固地基机理,在土体的应变位移关系上采用大变形假设,建立土体非线性动力平衡方程和整体流固动力耦合方程.在算例数值分析中给出了地基位移、孔隙压力在强夯作用时间内和空间中的变化分布规律,得到了夯锤的最大夯沉量,计算了夯击后地基孔隙压力的消散行为,计算结果与济南绕城高速公路强夯法施工现场的测试结果较符合.

| Abstract: | For the fluid-solid dynamic coupling question of foundation soil by dynamic consolidation, large deformation hypothesis on the relationship of strain and displacement was adopted to make a non-linear dynamic equilibrium equation and a fluid-solid dynamic coupling equation. In the analysis of a computed example, the distribution regularities of displacement and pore pressure of the foundation in the effective time and space were given. The maximum contact displacement was obtained. The dissipation of pore pressure was worked out. The results coincide the measured data of the highway around Jinan City of China perfectly. |
