Supporting Data and Spreadsheet Tool for Physically Interpretable Regression Equations for Stability of Homogeneous Slopes

This repository contains the dataset and spreadsheet-based tool (“SlopeSolve”) developed to support the study on physically interpretable regression equations (PIREs) for slope stability analysis of homogeneous slopes. The dataset includes validation results used to compare the proposed closed-form formulations with classical stability charts, limit equilibrium methods, and numerical simulations. The spreadsheet tool implements the proposed PIRE formulations and enables both deterministic and probabilistic slope stability analyses under drained and undrained conditions. The tool supports reliability-based design (RBD) using the first-order reliability method (FORM), and provides visualisation of key concepts including the limit state surface, reliability index, and design point. This dataset and tool are provided to facilitate reproducibility of the results presented in the associated manuscript and to support practical application of the proposed methodology. The associated manuscript is currently under review.
