A large amount of tsunami sludge was generated by the 2011 off the Pacific coast of Tohoku Earthquake, and the radiation contamination due to the nuclear power plant disaster also became a serious problem. It was necessary to decontaminate the radiation-contaminated waste and soil, and the radioactive pollutant will be stored at temporary storehouses. In this study, the relationship between failure strength property and permeability of the cover soil made of tsunami sludge was experimentally investigated.
