The steel sheet pile reinforcement method is often used as a countermeasure against settlement and lateral displacement when constructing embankments on soft ground. However, it has been reported that during Kumamoto earthquake (2016), some of the sheet piles that had been installed since the construction of the embankments contributed to seismic resistance, although they were not intended as an earthquake countermeasure. Therefore, by assessing the seismic performance of the steel sheet pile method, it is also expected to expand the applicable range of the construction method. In this study, a numerical investigation on the effect of the steel sheet pile reinforcement method with different embedment lengths was conducted against dynamic loading due to earthquakes, as well as the effect of settlement and lateral displacement at the time of static loading due to embankment construction. Numerical results indicate that the steel sheet pile reinforcement method enables us to obtain not only the isolated effect for the deformation during embankment construction, but also the aseismic effect by securing the proper embedment depth.
