该文以三维比奥固结理论为基础 ,较系统地介绍了利用有限元处理真空 -堆载联合预压加固高速公路软基的数值计算方法 ,对某加固高速公路软基的工程实例中路堤地基的应力应变、位移、孔压等的变化过程进行了数值分析和计算 ,计算结果表明 ,提出的处理方法具有较好的精度 Based on the theory of three-dimensional Biot consolidation, this paper systematically introduces the numerical calculation method of finite element method to deal with the soft foundation of expressway with vacuum-pile preloading. In a practical example of embankment reinforcement of soft ground of expressway, The stress and strain, displacement and pore pressure of foundation are analyzed and calculated. The calculation results show that the proposed method has better accuracy
