Abstract
This paper presents Multiple Linear and Machine Learning models of bearing capacity for strip footings at sandy clay slopes subjected to vertical loads. Several parameters are considered in the analysis, including footing width, embedment depth, unit weight, slope angle, internal friction angle, and soil cohesion. A finite element analysis is conducted to assess the impact of these factors. Additionally, an empirical prediction for bearing capacity is proposed. Machine learning techniques utilising various models are employed to analyse performance outcomes, with the Shapley Additive Explanations (SHAP) method used to quantify the contribution of each parameter. The results show that the empirical formulation for predicting ultimate bearing capacity can be effectively applied in engineering practice. Significantly, the findings indicate that the XGBoost model yields the most precise predictions of bearing capacity. The primary parameters influencing bearing capacity include embedded depth, width, unit weight, and internal friction angle, whereas vertical load and unit weight have a minimal impact.
