| Abstract : | Abstract. A model is presented for prediction of crack network geometry in clay soils. The starting point is the similarity between a crack network in rocks and that in soils, and, hence, principles of multiple crack formation in rocks can be used. The model estimates the mean crack width, crack cross-section area, and crack volume. Special verification of the model was done with published data on these characteristics in the micro-shrinkage depth range. Agreement between the data and the model predictions for these depths is satisfactory. |
