Influence of Underground Tunnels on Normal Fault–Foundation Interaction

Key Points

• Foundation interactions with normal faults exhibit significant changes due to nearby underground tunnels, highlighting the importance of geotechnical considerations.
• Ground movement associated with normal fault activity can be exacerbated by the proximity of underground tunnels, affecting structural integrity.
• Stress distribution patterns indicate that underground tunnels alter the typical behavior of normal faults, necessitating adjusted engineering practices.
• This analysis suggests potential risks related to underground infrastructure, underscoring the need for thorough geotechnical assessments.
