摘要
软粘土的重要特性之一是其应力－应变关系与时间有关。采用粘弹塑性本构模型描述软基上吹填土边坡的蠕变特性，并建立了相应的有限元分析模型。通过实例研究，得出了有益的结论。
One of the important mechanical behaviors of soft clay is time-dependentcy of the stress-strain behavior. A visco-elasto-plastic rheological model is presented for describing a time-dependent behavior of dredger fill slope on soft foundation. And It is implemented in a finite element program. As an actual example, the visco-elasto-plastic behavior for a filled slop of soft clay is studied and some valuable conclusions are drawn.
