This eBook includes a practical guide on:

Choosing Between 2D and 3D Analysis: This eBook outlines the pros and cons of 2D vs. 3D slope stability models, helping engineers decide which approach suits their project based on geometry, complexity, and data availability.
Applying LEM and FEM Methods: It provides detailed guidance on when and how to use the Limit Equilibrium Method (LEM) and the Finite Element Method (FEM), including their strengths, limitations, and practical applications.
Combining LEM and FEM for Deeper Insight: A step-by-step guide shows how to integrate LEM and FEM to enhance analysis accuracy, reduce conservatism, and better understand complex failure mechanisms.
Running Slope Stability Analyses in GeoStudio and PLAXIS: The eBook walks through setting up and executing slope stability models in both software platforms, including mesh refinement, pore pressure considerations, and interpreting safety factors.
Case Studies for Real-World Application: It includes practical case studies—such as open pit mining and road construction—demonstrating how integrated modelling approaches solve complex geotechnical challenges.
Leveraging the Seequent/Bentley Ecosystem: The guide explains how to integrate geological models from Leapfrog and manage data with Seequent Central, enabling a connected, collaborative geotechnical workflow.

It’s a question that every geotechnical engineer asks themselves. And it can be tricky to narrow down which method can give you the perfect balance of efficiency and accuracy for your project.

But, with the right tools on your side, it’s easy to switch between the two most relevant methods — the Limit Equilibrium Method (LEM) and the Finite Element Method (FEM) — according to the needs of your project.

In this e-book, we’ll dive deeper into the benefits and drawbacks of each form of analysis. And crucially, we’ll show how each of these techniques — 3D and 2D analysis, FEM and LEM — are complementary. Together, they can give engineers the flexibility, accuracy, and insight they need to keep people safe and projects moving.
