- Abstract:
-
The modified linear relationship between the change of void ratio and the logarithmic time was intro-duced to simulate the rheological behaviors in the consolidation process of normally consolidated and saturatedclays,one-dimensional rheological consolidation equation was obtained based on Hansbo’s formula for non-Darey flow,and numerical analysis was performed by using the finite volume method.Then the effects of rheo-logical parameters on the one-dimensional consolidational behaviors of normally consolidated soils were investi-gated. The numerical calculation results indicated that the rheological behaviors of these soils delay the overallrate of dissipation of the excess pore water pressure in these soil layers resembling the effect of non-Darey flow,and the phenomenon similar to the Mandel effect appears, i.e. the excess pore water pressure increases in theplace far away from the drainage boundary at the beginning of loading. In addition , the loading value can alsoinfluence the consolidation behaviors of these soil layers.
