Effect of Seafloor Instability on Offshore Pile Foundations

摘要

The paper employs a modified non-linear boundary element approach to analyze theresponse of offshore piles subjected to external soil movements arising from submarine slides. Theoretical solutions for a realistic hypothetical offshore pile computed by the approach are presented and discussed. The analysis is then used to analyze the behavior of two full scale offshore piles in submarine slide areas, and reasonable agreement is found between observed and theoretical behavior.
