Abstract
The consolidation is important with regard to the stability and settlement of soils compacted wet of optimum moisture content. In this paper, the problem is restricted to the consolidation of partly saturated soils compacted wet of optimum moisture content.The relation between pore pressure and total stress is obtained, assuming that the pore fluid which is a mixture of pore water and pore air is a homogeneous and compressible fluid.The consolidation equation for partly saturated soils is obtained, in which the compressibility of pore fluid, the variation of permeability with degree of saturation and effective stress, and the variation of volume change with effective stress are taken into account. It is shown from the results of numerical solution of the consolidation equation that the consolidation progresses more rapidly with increasing initial pore pressure, coefficient of volume change, and/or degree of saturation.The pore pressure during consolidation is measured, and it is observed that consolidation progresses more rapidly as the initial pore pressure, and or coefficient of volume change increase.
