Regression Tools to Quantify the Swelling Pressure of Expansive Soil in Tebessa Region (Algeria)

This study aimed to quantify the pressure generated by the clayey soil of Tebessa region in order to use it as a parameter for particular construction works. The statistical, principal component analysis and regression tools were used as simple techniques taking into account the combined effects of the soil properties on swelling behavior and dealt with the swell pressure models. In the selection of independent variables; regression analyses were carried out and the multi-colinearity problem was considered, in the multiple regression analysis. Regressors were added to obtain the final model. The obtained model is acceptable and gives the best results when compared to previous cited models in the literature. The regression analysis technique is a powerful predictive tool for assessing the swell pressure for all soil conditions.
