Investigation of parallel joint density thresholds for granite tunnel failure based on physical model experiments and multiscale monitoring techniques
Abstract Joint density significantly influences the failure modes of hard rock caverns, yet the underlying mechanisms remain poorly understood. This study systematically investigates the impact of parallel joint density on the failure behavior of hard rock tunnels by integrating physical model tests...
