To prevent ground settlement, lateral deformation and upheaval that occur in the surroundingground due to banking such as levees and roads on soft ground, the countermeasure with sheet pile walls drivencontinuously into the bearing stratum to form stress discontinuity between the embankment and the surround-ing ground is conventionally used in Japan. In this paper, PFS (Partial Floating Sheet-Pile) method in whichnumber of sheet piles driven into the bearing stratum enables to be reduced is introduced. PFS method enablesto improve both construction cost and driving performances based on the reasonable design method which satis-fies the requirement in and around the embankment. The several field test results are reported and a simplifieddesign method with bilinear model as soil behavior is also described.
