Abstract. This research presents numerical simulation approach for predicting the values of unsaturated soil parameters with low water content. In order to understand how unsaturated soils behave and to create the suction stress curve, the proposed model can be used to predict the relationship between the suction stress and the filling angle θ, in terms of particle separation distance. The updated model assumes that all the particles are equally dispersed spheres of the same size. In this study, the updated model is exclusively applied to simple cubic packing order with zero contact angle. The model may also be used to predict matric suction, effective stress parameter χ and tensile strength while combining experimentally determined soil properties. This removes the requirement for sophisticated measuring devices or specific test procedures to illustrate how the separation distance affects the behavior of unsaturated soils.
