The 2010-2011 Canterbury earthquakes (New Zealand) provided many case histories of liquefaction and lateral spreading. In the aftermath several seismic dilatometer (SDMT) tests were performed in Christchurch within the scope of the Ground Improvement Trials Report for the Earthquake Commission (EQC). SDMT-based liquefaction analyses were conducted to validate the use of existing correlations for deriving the cyclic resistance ratio CRR from the horizontal stress index Kd and to increase the CRR-Kd case history database. The results obtained at different sites show a variable trend and point out the need for further investigation on the influence of factors, such as the fines content, not taken into account by current CRR-Kd correlations.

Abstract
The 2010-2011 Canterbury earthquakes (New Zealand) provided many case histories of liquefaction and lateral spreading. In the aftermath several seismic dilatometer (SDMT) tests were performed in Christchurch within the scope of the Ground Improvement Trials Report for the Earthquake Commission (EQC). SDMT-based liquefaction analyses were conducted to validate the use of existing correlations for deriving the cyclic resistance ratio CRR from the horizontal stress index Kd and to increase the CRR-Kd case history database. The results obtained at different sites show a variable trend and point out the need for further investigation on the influence of factors, such as the fines content, not taken into account by current CRR-Kd correlations.Pubblicazioni consigliate
