摘要: The resistivity piezocone penetration test (RCPTU) does not only include a conventional test, but also provides continuous profile of electrical resistivity. Therefore, RCPTUs have the potential for wide application in environmental geotechnics. Electrical is fundamental parameter characterizing soil conductivity, one inherent physical properties soil. objective this study was to evaluate subsurface spatial variability using RCPTU data and laboratory tests. Normalized proposed developing relationships between behavior type index, relative density cyclic resistance ratio. These are used evaluation variability. index can be represented by function normalized R cone tip resistance. Additionally, there positive correlation ratio adopting effective.
