numerical simulation of soil deformation due to liquefaction using finite element method

liquefaction of sandy soils during disastrous consequences, such as significant structural damage and loss of life. considerable advances have been made in recent years in the area of numerical analysis of soil liquefaction. has received considerable attention since the experiences in japan and alaska during the mid 1960s. in this paper, the behavior of sand due to earthquake finite element method and the use of the poorooshasb and pietruszczak (1985) for numerical simulation. then soil deformation is investigated during earthquake and after soil liquefaction. model it can be seen that the major deformation of the soil without applying the overhead in the horizontal direction, the maximum is at ground level and continues deep in the nonlinear and descending direction, but the vertical deformation, which is very low, is only 2 meters ear model is valid to the soils without overload and prone to being liquefaction.
