Abstract
It is required to determine proper countermeasures of a railway embankment by evaluating failure mode of the embankment that is selected as that assumed to fail during earthquake in order to carry out seismic countermeasures for preventing failure of the embankment. Although a study on selection of the embankment that assumed to fail is performed, it is confirmed that position of slip surface calculated by stability analysis based on the circular slip surface that does not include progressive failure of a soil can be deeper than that obtained from a model experiment. Hence, in this study, numerical study utilizing mesh free method that can deal with the progressive failure and residual deformation of the embankment was performed in order to investigate influence of the progressive failure on the failure mode of the embankment.
