Understanding how tunnels respond to varying ground conditions and seismic effects is essential for safe and reliable underground construction. In practice, engineers must evaluate how geological uncertainty influences deformation, support performance, and long-term stability often requiring comparative numerical analysis to guide decisions.

This session examines how tunnel behavior changes under different soil and rock conditions, as well as under seismic loading, using practical numerical modeling examples. The focus is not only on running the analysis, but on how to interpret results and translate them into field-ready design strategies.
