Slope Stability Analysis Input Sheet (Excel)

Slope stability analysis in open-pit and waste dump contexts relies on accurate, well-documented inputs—including slope geometry (bench height, batter angle, crest-to-toe distance), rock mass properties (unit weight, cohesion, friction angle), discontinuity characteristics (orientation, spacing, persistence, condition), and groundwater conditions (phreatic surface elevation, pore pressure ratio ru). The Excel Input Sheet structures these variables into logically grouped sections—geometric configuration, material property tables, failure surface assumptions, and environmental loading—with built-in validation (e.g., data type checks, unit consistency alerts) and metadata fields (e.g., source references, date of entry, responsible engineer). It often integrates with downstream tools via defined named ranges or exportable CSV outputs, enabling seamless transfer to software such as RocScience Slide2, Phase2, or custom MATLAB/Python stability solvers. Furthermore, version-controlled sheets support regulatory compliance (e.g., MSHA or Australian Mining Guidelines), peer review, and iterative design updates during pit pushbacks or geotechnical monitoring campaigns.
