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.
