What You'll Take Away

A clear workflow for cut & cover tunnel modeling in real project environments

Practical criteria for choosing and calibrating soil constitutive models

How to evaluate ground behavior and adjust support systems efficiently

A repeatable approach for deterministic and sensitivity-based design decisions

Description

Cut & cover tunnel structures are frequently used for mine portals, where the transition between surface excavation and underground support requires precise control of ground–structure interaction. In these environments, geology, groundwater, and construction sequencing play a critical role in stability and deformation behavior. Designers often need to evaluate deterministic outcomes while also performing sensitivity studies to understand how changes in soil parameters influence performance. Selecting and calibrating soil constitutive models is essential to ensure that the analysis reflects realistic ground behavior.

This session presents a practical, field-driven approach to cut & cover tunnel design for an underground mine portal using MIDAS GTS NX. You’ll learn how to set up the model, assess ground response, compare design alternatives, and efficiently adapt support systems based on real project considerations.

 

Who Should Attend

  • Geotechnical / Tunnel Engineers working on cut & cover or portal structures

  • Underground Structure Design Engineers needing practical modeling and sensitivity evaluation

  • Mining & Underground Project Engineers designing or reviewing mine portal access structures

  • FEA / Numerical Analysis Engineers seeking guidance on soil constitutive model selection and calibration 

 

Why Should Join 

  • See how cut & cover tunnel design decisions are made in real projects

  • Learn practical workflows for model setup, verification, and adjustment

  • Understand when and how to apply deterministic vs sensitivity design approaches

  • Gain clear guidance on selecting and calibrating soil constitutive models for reliable results
