Study on the Water Inrush Failure Characteristics and Disaster-Inducing Threshold of Tunnels Overlying Karst Caves under Stress-Strain-Seepage Coupling
Tunnels traversing overlying water-filled karst caves face high risks of water inrush disasters. This study develops a stress-strain-seepage coupling model for karst tunnel surrounding rock, centered on a four-stage linear strain hardening-softening model derived from triaxial tests on intact lime-stone.
