Abstract: This paper summarizes the development of experiments on the fluid dynamic characters of liquefied soil as well as recent numerical simulations based on computational fluid dynamics (CFD) about seismic liquefaction. The cubic interpolated pseudoparticle (CIP) numerical method, which is emphasized herein, is active at present and is available to simulate the flow state of liquefied soil with high accuracy. Compared with conventional solid mechanics, CFD has significant advantages in the following three areas on liquefaction analysis: (1) large deformation of soils; (2) parameters of liquefied soils; (3) deformation of structures in liquefied soils. In future research, the applications of CFD to the seismic liquefaction, should take into account soil behaviors in the status before liquefaction and dynamic pile-soil-structure interactions during liquefaction.

Key words: seismic liquefaction, computational fluid dynamics (CFD), liquefied soil, viscous fluid, experiments, numerical simulations
