Abstract

In many rapidly urbanizing countries, deep excavations often cause damage to nearby utilities, such as roads, manholes, and buried pipelines. Earthquakes can also devastate underground lifelines, as seen in the 1999 Chi-Chi earthquake in Taiwan and the 2011 Tohoku earthquake in Japan. These issues have raised concerns about the response of buried pipelines to deep excavations and seismic effects. To address these concerns and promote the development of resilient cities, this study conducts numerical simulations to investigate the response of buried pipelines to deep excavation and seismic conditions using PLAXIS. A case study involving a deep excavation project in soft clay is included to validate the numerical results, analyzing excavation-induced ground surface settlements and pipeline movement with different sizes. Lastly, the study discusses the soil and dynamic responses of buried pipelines following excavation. The numerical results and findings from the current study can be a valuable reference for future engineering design and planning.
