Popis:	This paper presents practical approaches for developing design response spectra in a liquefiable site and for evaluating liquefaction-induced ground settlement and lateral deformation for a 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, CA, USA. The site encompasses approximately 6.5-acre (2.63-hectare) 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 using the methodologies of the current state of practice. Several site retrofit measures to mitigate liquefaction-induced ground deformations were discussed and recommendations were made.
