Slope stability analysis model
noun phrasePronunciation: /sloʊp stəˈbɪləti əˈnæləsɪs ˈmɑdəl/
A computational or analytical framework used to evaluate the structural integrity and safety of reclaimed mine slopes under static and dynamic loading conditions. Models incorporate geotechnical parameters such as soil friction angle, cohesion, and pore pressure to predict failure probability and inform design modifications.
Plain English
A computer or mathematical tool that predicts whether reclaimed slopes will remain stable or collapse.
Etymology & History
Usage
"The slope stability analysis model indicated that a 2H:1V slope angle would achieve a factor of safety greater than 1.5 under saturated conditions."
Style guide notes: Specify the analysis method (limit equilibrium, finite element, etc.) and factor of safety threshold used.

Frequently Asked Questions
What geotechnical parameters do slope stability models require?
Soil friction angle, cohesion, unit weight, pore pressure, and groundwater conditions are essential inputs.
What is an acceptable factor of safety for reclaimed slopes?
Typically 1.3-1.5 for permanent slopes depending on consequences of failure and regulatory requirements.
Why Test Candidates on This?
Slope stability analysis models are tested in geotechnical engineering, reclamation design, and civil works courses.
