Abstract

In this research work the complicated phenomena of swelling behaviour of expansive soils is modelled using an evolutionary approach proposed to develop a structured polynomial model for predicting the lateral swelling pressure of soils on retaining structures considering the effect of EPS geofoam implemented to control the transmitted lateral swelling pressures to the structures. The proposed evolutionary polynomial regression technique possesses the capability of generating a transparent and structured representation of the behaviour of a system from raw data. Field measurement data from literature was used to develop the proposed model. Comparison of the developed model predictions with the field measurement data revealed that the proposed model is robustly capable of capturing, predicting and generalising predictions to unseen data cases. The merits and advantages of the proposed methodology are also discussed.
