Study on the Asymmetric Failure Characteristics and Failure Mechanisms of Surrounding Rock During Excavation of a Deep Buried Small-Clearance Tunnel

Study on the Asymmetric Failure Characteristics and Failure Mechanisms of Surrounding Rock During Excavation of a Deep Buried Small-Clearance Tunnel

In deeply buried, small-clearance tunnels, the failure of the surrounding rock is profoundly influenced by the superposition of stresses and the cumulative disturbance effects from multiple blasting events. Consequently, the failure characteristics and mechanisms of the surrounding rock are highly c...
