Geotechnical and seismic hazard study for a marine site development in southern California

Abstract

This paper presents results of a geotechnical and seismic hazard study for a marine site development consisting of four main structures, which are up to 12-story high over a two- to three-level parking structure in Marina Del Ray, California, U.S.A. The site encompasses approximately 6.5-acre area bounded by two channels and is underlain by typical marine soils including soft clay and liquefiable sand. Extensive field exploration and laboratory testing were performed to investigate site-specific geotechnical conditions. After developing site-specific design ground motion parameters, liquefaction potential, liquefaction-induced settlements and lateral spreading were evaluated. Several site retrofit measures to mitigate liquefaction-induced ground deformations were discussed and recommendations were made. © 2008 Science Press Beijing and Springer-Verlag GmbH Berlin Heidelberg Geotechnical Engineering for Disaster Mitigation and Rehabilitation.
