Study on Coastal Levee Reinforcement Using Double Sheet-Piles with Partition Walls

There is a fear that coastal levees will sink by liquefaction due to large earthquakes such as the Nankai Trough earthquake in Japan. To overcome this damage, as one of the major countermeasures, the application of double sheet-pile walls to coastal levees has been proposed. In this study, to enhance the performance of this countermeasure, the authors focus on installing partition walls perpendicular to sheet-piles. By the shaking model test and numerical analysis, remarkable inhibition of the levee deformation/settlement was confirmed.
