Seismic Response Analyses of Life-Line Infrastructure with Emphasis on Embankment Systems in Southern California
Publication: Geo-Extreme 2021
ABSTRACT
Ensuring the integrity of a country’s life-line infrastructure is necessary to protect surrounding communities in case of disaster, and limiting the extent that unanticipated consequences could have on various aspects of life. Embankment dam systems across the country are an essential component of life-line infrastructure. In this study, numerical models were developed using finite-element modeling to investigate a series of embankment dams in southern California. The models were then verified with real accelerometers data provided by the California Strong Motion Instrumentation Program (CSMIP). The results from this study identified areas of weakness and instability on the dam that posed the greatest risk for its failure. Following this study, the numerical model can now be used to predict the dam’s response to future earthquakes, develop plans for its remediation, and reevaluate the emergency response in case of disaster, and ultimately, having an understanding of the potential outcomes that can occur in case of infrastructure failure.
