Abstract
This paper describes a case history where potential earthquake induced liquefaction is of concern at a site where a major housing development is planned. The site comprises inter-layer saturated loose to medium dense sandy silts, silty sands and soft clay layers to a depth of 35 ft. Liquefaction potential at the site was evaluated through the use of cone penetrometer test (CPT) logs and standard penetration test (SPT) data. Results of DESRA-2 effective stress site response analyses were also used to determine pore pressure response at the site for a given design earthquake, and are compared to liquefaction assessments conducted using the empirical SPT approach. Methods for determining post liquefaction settlement and potential surface manifestation of liquefaction are described along with the methods used to assess recommendations for site remediation.
