This paper describes the liquefaction triggering relationships by NCEER (1997) and Youd et al. (2001, 2003), Idriss and Boulanger (2008) and Boulanger and Idriss (2014), used to assess the susceptibility of the loose sands to liquefy. For the Idriss and Boulanger (2008) and Boulanger and Idriss (2014), the site-specific fines content correlation and carbonate content of the sands was incorporated in the analysis. The paper then demonstrates the use of CPTu and SCPTu soundings and shear wave velocity measurements to develop soil capacity for the site seismic input data. Factor of safety against liquefaction calculations are performed using the CPTu data and post-liquefaction settlements are calculated based on the normalized CPTu results and the factor of safety.
