What You'll Take Away

A clear understanding of NATM philosophy and its implications in numerical modeling

In-depth understanding of ground-structure interaction principles specific to tunnel excavation

Evaluation of tunnel stability, convergence behavior, and support effectiveness

Workflow optimization tips for accurate and efficient modeling in GTS NX modelling

Description

The New Austrian Tunnelling Method (NATM) is a widely adopted approach that leverages the natural strength of the surrounding rock mass through controlled deformation and timely support. Accurately capturing the interaction between ground and support systems is essential to ensure safety and performance in complex geological settings.

This webinar will demonstrate how 2D and 3D finite element simulations in GTS NX can effectively model the staged excavation, stress redistribution, and support installation central to NATM. Attendees will gain insights into realistic simulation workflows, and how ground-structure interaction influences tunnel behavior and design outcomes.

 

Who Should Attend

  • Geotechnical and Tunnel Engineers involved in NATM or sequential excavation

  • Civil Engineers working on metro, highway, and infrastructure tunnels

  • Researchers in tunneling, soil-structure interaction, and underground

  • Consultants and project authorities focused on tunnel safety and design

 

Why Should Join 

  • Understand how NATM is simulated realistically in both 2D and 3D environments
  • Learn how sequential excavation, support placement, and ground deformation are modeled
  • Explore the benefits and use cases of GTS NX in tunneling projects
  • Improve your ability to analyze, interpret, and apply simulation data for tunnel design
  • Discover ways to optimize models for accuracy and efficiency in real projects
