Probability distribution characteristics of vertical hydraulic conductivity in substrate of lake areas;

The differential governing equations for the consolidation of composite ground with granular columns are established,which can consider the gradual variation of horizontal permeability coefficient of soft soil in a drainage influential zone caused by disturbance during granular column construction.

A general analytical solution is given to the consolidation problem for the composite ground with granular columns under time-dependent loading and arbitrary variation of horizontal permeability coefficient in the soil of drain influence zone with radial distance.
