ABSTRACT
This paper describes the geotechnical aspects of liquefaction failures in two areas of San Francisco. Utility perfomance during the two earthquakes is discussed in a companion paper appearing elsewhere in these proceedings. Both papers are based on the results of a liquefaction atudy perfomed for the city and County of San Francisco.(AU)

This paper reports on vulnerability measures of underground piping subjected to area-wide deformations, and the spectrum of mitigation measures developed as part of this project. Due to limitations of space, only two of the areas studied, the Marina and Sullivan Marsh areas, are discussed. In order to do this, we next describe the underground utility systems considered as part of this project, summarize our evaluation of utility damage, and review the mitigation options developed for the project.(AU)
