Seismic response and failure mechanism of pile foundations at different relative positions and rock-socketed depths on deep deposit slopes

Key Points

• Seismic response varies significantly with different rock-socketed depths and relative positions of pile foundations on slopes.
• Key evidence showed that altering the rock-socketed depth could change failure mechanisms significantly under seismic conditions.
• Analysis of failure mechanisms focused on how pile foundations interact with deep deposit slopes during seismic events.
• These findings highlight the need for tailored engineering solutions to enhance pile foundation resilience against seismic activity.
