The effectiveness of drain method on preventing sand boil was proved by previous studies (Nguyen et al., 2019; Sassa et al., 2017) by using static seepage centrifuge tests, while in this study a series of dynamic model tests are conducted, to reproduce sand boil due to liquefaction and to determine the performance of drain method on suppressing this behavior.
