大面积预压堆载的弹塑性有限元分析

Finite element analysis of elasto-plastic for large-area pre-loading field

采用比奥(Biot)固结理论对大面积堆载场地进行有限元分析,对不同的土层采用不同的本构模型,更接近土体的实际情况.并与实测结果进行比较,得到比较满意的结果.

This essay take the biot consolidation theory as the guide. According to the different qualities of the soil, we can use finite element method and different soil models to calculate the large area loading field. This method is more approached to the true condition, and was compared with the real final results that is contented.
