Abstract

This paper presents a critical states oil model used for the analysis of variations in water content associated with footing load. It is essentially a modified version of the Wheeler & Sivakumar( 1995)'s model. An experimental validation of the model based on tests by Sivakumar(1993) is discussed here and studies a surface foundation lying on unsaturated soil subjected to water level fluctuations. Two hypothetical cases have been studied: a rise in the groundwater and a drop in suction from the ground surface, as in the case of rainfall or surface seepage from leaks in water pipes.
