【摘要】 用有限单元法数计算了黄土路基单点多次夯击过程,在算例中给出了邯长高速公路夯击过程中地基内各点的应力、位移变化规律,并将计算结果与强夯法施工现场的测试结果作了比较.结果表明:模拟计算较好地反映了路基土体在强夯加固过程中的物理、力学参量的变化规律.更多还原

【Abstract】 The sigle-point ramming process of loess road foundation was simulated by the finite element method. The distributions of stress, displacement and pressure in the foundation during dynamic consolidation were provided with a sample of Han-Chang Expressway. Computational results were compared with the measured data at the consolidation site. It is shown that the numerical simulation can exactly reveal the change of physical and mechanical parameters of the collapsible loess foundation during dynamic consolidation.更多还原
