영문 초록

Vertical hydraulic barrier is essential component to prevent leachate leakage in offshore containment facilities. Double steel pipe sheet pile is one of effectively used as vertical hydraulic barrier in Japanese offshore waste landfill sites. In this study, two-dimensional finite element analysis was performed to evaluate contaminant transport characteristics considering advection-dispersion-diffusion through double steel pipe sheet pile according to tidal fluctuation and different water level in landfill by using SEEP/W and CTRAN/W. Numerical analysis results indicate that water level in landfill should be maintain similar or lower compared with sea water level to prevent the leakage from landfill to sea. In addition, double steel pipe sheet pile was effective to prevent contaminant leakage to outside sea since filling zone between two barrier act as buffer zone for spreading contaminant.
