Abstract
In this study, the spatial variability of the strength and permeability inside and underneath a river dike are addressed. Cone penetration tests (CPTs) were conducted at the river dike site, which has piping histries. In addition, CPTs were conducted in the laboratory as model tests on soil sampled from the river dike site, and permeability tests were also conducted on the same samples. Based on the laboratory tests, the relationship between the CPT results, which include the tip resistance, the side friction, and the pore pressure, and the permeability is derived. The relationship is applied to the in-situ test results. In conclusion, the spatial variability of the strength and permeability of the test site is evaluated with a geostatistical simulation technique.
