Performance estimation of a shallow foundation on an unsaturated expansive soil slope subjected to rainfall infiltration

In the last two decades, there has been a significant increase in infrastructure development on slopes of hilly regions world, due to population growth. There are many infrastructures unsaturated expansive slopes, especially semi-arid and arid regions. Rainfall infiltration is one major factors that contributes slope foundations failures with soils. current study, rational approach proposed considering combined influence foundation-slope behavior based principles soil mechanics. This achieved by novel numerical modelling using commercial software Geo-studio investigate performance strip foundation located top subjected various rainfall conditions. Hydro-mechanical coupling analysis conducted evaluate water stability limit equilibrium method. Comparisons made between both bearing capacity, before after infiltration. Different failure mechanisms system presented without loading for scenarios. Results summarized this paper helpful geotechnical engineers understanding shallow
