N2 - Liquefaction of sand is the main cause of failure for earth structures during earthquakes. Some past research showed that the fabric anisotropy of soils in the ground can cause different responses to both static and dynamic loading. The inherent fabric anisotropy of sand due to the deposition history and pattern may also affect the liquefaction potential of the ground. In this study, a group of earthquake centrifuge tests was performed on models of a level ground to investigate its seismic response with the soil deposited by different angles. A special rigid container was designed and used to prepare the models. It was found that the fabric anisotropy greatly influenced the response of the ground in displacement, acceleration, and excess pore pressure. The models with larger deposition angles had higher liquefaction potential. The results show that liquefaction evaluation of a sand layer should take into account the influence of fabric anisotropy caused by its deposition history and pattern.
