摘要

This study investigated the respective correlation coefficients between pore water pressure (PWP) development in sandy soil and 41 CAV-based (cumulative absolute velocity) ground motion intensity measures and peak ground acceleration (PGA). Based on 720 site response analyses using DEEPSOIL with 120 (real) strong ground motions and the (real) borehole data (e.g., soil unit weight, shear-wave velocity) at six sites, the result shows that cutoff CAVs with cutoff acceleration of 0.02–0.04 g are better correlated with PWP developments in sandy soil than the (original) CAV without cutoff acceleration. It also shows that PGA is poorly correlated with PWP developments, having the lowest correlation coefficient among the 42 intensity measures.
