In order to study the shrinkage process of clayey soil, we perform a modified laboratory test allowing to measure simultaneously and continuously the vertical displacement and the weight of natural statespecimen. The experiment was conducted on undisturbed clayey specimen. Using the experimentalresults, and on the basis of the existing relation between the soil water content and its structural evolution, we proposed an analytical model allowing the analysis of the soil shrinkage curve.
