Abstract:

Combining large number of indoor consolidation and odeometer test data of Ningbo soft soil, using partial differential finite element software FLEXPDE, and taking into account complicated geometry and material nonlinearity of soil, the characteristic of soil consolidation is investigated. Under the conditions of different ratios of compression index to permeability index, analytical solutions and numerical solution as well as the distribution of effective stress and void ratio with height are obtained. The results showed that numerical solution fully taken into account the complex nonlinearity of soils; and results more in line with actual conditions when the ratio of compression index to permeability index is not equal to 1; the results are consistent with the results of Gibson’s in 1981 when ratio is 1; it’s more safe to forecast the effective stress and the consolidation degree when considering the complex nonlinearity of geometry and materials of soil.

Key words: analytical solution, numerical solution, large deformation, one-dimensional consolidation, complex nonlinearity
