Numerical Analysis of Vacuum-heaped Load Combining Precompression in the Consolidation of Soft Clay

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 。

This paper introduces sysmetically the numerical calculation of vacuum heaped load precompression in the consolidation of soft clay with FEM,based on the Biot theory on three dimensional consolidation.The numerical analysis and calculation of the changing procession of displacement,stress strain,pore space water press in a project about consolidated motorway states that the method has high precision.
