There is fear that coastal levees will sink by liquefaction due to large earthquake such as Nankai Earthquake in Japan. To overcome this damage, as one of major countermeasures, the application of double sheet-piles wall to coastal levees has been proposed. Authors confirmed that the settlement of coastal levee was reduced remarkably using partition walls connected to double sheet-piles, based on model tests and 2-D numerical analyses. However, the influence of the interval of partition walls has been discussed in the framework of 2-D numerical analyses. So, in this study, authors investigated 3-D behavior of levee deformation during earthquake using 3-D numerical analysis. As a result, authors confirmed that long interval of partition walls increased settlement near the center of levee between partition walls.
