Slope Stability and Excavation Analysis in MIDAS GTS NX

Overview

This MIDAS Academy session covers two of the most common checks in geotechnical design – the stability of slopes and the stability of excavations – and shows how to carry them out in MIDAS GTS NX.

Starting from the principles of slope failure, you will see how the factor of safety and the critical failure surface are obtained from a finite element model, in 2D and in 3D. The session then moves on to staged excavation: you will follow how the factor of safety changes from the in-situ state, through each excavation step, to the final state, and how retaining structures and reinforcement affect the result.

Key highlights include:

• Slope Stability Fundamentals: Failure mechanisms and the factors that govern slope behaviour
• Strength Reduction Method: Obtaining the factor of safety and the critical failure zone from finite element analysis
• 2D and 3D Models: When a 3D slope model is needed and how terrain and soil layers are built in GTS NX
• Staged Excavation: Construction stages from the in-situ state to the final excavation level
• Factor of Safety per Stage: Tracking how stability changes with each excavation step
• Retaining Structures & Reinforcement: Including walls and reinforcement in the stability check

Join us in Iași to model a slope, run the stability check and follow it through every excavation stage!
