The hydroconsolidation option is only used for soils that are very sensitive to moisture content and experience swelling or collapse due to wetting.
The hydroconsolidation settlement calculation is influence by the curve that the user provides for the pressure vs ∆ void ratio relationship for the soil. If the curve has a steep gradient, this will create large amounts of settlement.
The predicted settlement from the elastic solution does not include the effect of hydroconsolidation and is based on small strain theory which neglects such effects.
The effects of hydroconsolidation will influence all the soil layers within the hydroconsolidation region. Due to the change in strain in these layers, the settlement calculation will be affected.
