Tunnel collapse

A tunnel collapse occurs when the structural integrity of a tunnel fails, causing it to give way or fall in. This can happen due to unstable ground conditions, weak or poorly designed support systems, water infiltration, or unexpected geological features. When a collapse occurs, it can block passage, trap workers, and cause damage to nearby structures. Engineers design tunnels with support mechanisms like beams and lining to prevent such failures. Regular inspections, proper planning, and monitoring soil and rock stability are vital to reduce the risk of collapses and ensure safe tunnel construction and operation.
