| Research Abstract |
Since Japan has limited land space, it it essential to utilize closed waste landfills and naturally contaminated soil as resources. In this research, experimental studies were conducted to characterize waste ground, bottom clay layer and contaminated soil. The following items are mainly verified: 1) since waste ground can has as high strength as sandy ground from the viewpoint of initial stiffness and internal frictional angle, spread foundations are applicable according to type of structures, 2) when pile foundations are installed to reach the bearing layer beneath a bottom clay layer, the channel between the steel and the clay closed enough under the normally consolidated condition by the effect of clay deformation, and 3) the bentonitic barrier material, such as GCL, can maintains extremely low hydraulic conductivity even against acid rock drainage containing heavy metals, and can mitigate outward leakage of heavy metals.
