Sahilkent (Bafra, Samsun) yöresindeki alüvyal zeminlerin sıvılaşma potansiyelinin CPT verileri kullanılarak araştırılması

In this study, liquefaction potential of the alluvial soils consisting clay, silt, and sand sized materials in Sahilkent (Bafra, Samsun) area was investigated using CPT data. Within scope 20 boreholes each having a depth 15 meters were drilled throughout Bafra district, one undisturbed soil sample obtained per meter from 5 these located area. Wet sieve, hydrometer, plastic limit, liquid natural water content determinations conducted on samples with high silt content. preliminary evaluation, it determined that there is some regions at different depths, order to perform detailed analyses, 15-meter-deep CPTu carried out 1 distance those borehole locations. tests, data including cone tip resistance, sleeve friction, effective stress, relative stiffness, etc. recorded every cm, average values for used analysis. Liquefaction analyses an earthquake scenario Mw = 7.2 15-meter layer study determined. As result no will occur region. It thought fine-grained alluvium, fact existing clean levels are between layers increase resistance against liquefaction.
