Abstract

The sheet pile wall is used popular for coastal projects, and it is normally applied suitable for the ground had average or weak bearing capacity. Currently, when analysis and design this structure type under earthquake loading, almost documents and standards recomment to use response spectrum method, without much mention of the time-history method. This paper presented the method to evaluate the behavior of sheet pile quay wall using time-history method including liquefaction of soil by PLAXIS 2D program. The analysis was conducted based on the Vietnam standard and some foreign standards. The results focused on analysis and evaluate displacement and deformation of quay wall, the increase of excess pore pressure in the backfill with the time and liquefaction potention of the soil.
