堆载加固软基的有限元分析

采用大型有限元软件ABAQUS模拟了一个实际工程,为了简化计算,将实际的三维问题等效转化为平面应变问题,并采用摩尔—库仑理想弹塑性本构模型分析了该问题,发现与实际的量测值具有较好的一致性,说明采用摩尔—库仑理想弹塑性本构模型能够很好的预测堆载作用下软土地基的沉降和变形。

The finite element analysis of accumulating load reinforcement soft foundation

A practical engineering was stimulated with large finite element software ABAQUS. In order to simplify calculation, the practical three dimensional problems were transferred to plane strain problems. The problem was analyzed with Mohr-Coulomb ideal elasto-plastic constitutive model, and it found that which had better agrocment with practical measured value. It illustrated that the Mohr-Coulomb ideal elasto-plastic constitutive model was better to forecast the soft soil foundation settlement and deformation under accumulating load.
