Experimental investigation on corrosion-induced deterioration of secondary lining of mountain tunnel under the effects of sustained loads and existing cracks

Puntos clave

• Deterioration significantly increases under sustained loads, impacting tunnel safety and integrity.
• Crack presence exacerbates corrosion effects, leading to greater distress in secondary lining.
• Experimental investigation assesses new deterioration models for improved infrastructure resilience.
• This highlights the need for early detection and maintenance to prevent structural failure.
