| Popis: | A logistic regression model has been developed forevaluation of soil liquefaction by the use of cone penetration test (CPTu,PCPT) on data collected from Adapazarı, Turkey. The model inputs are the cleansand equivalent normalized cone tip resistance (qc1N,cs) and cyclic stress ratio corrected for momentmagnitude of 7.5 earthquake (CSRM=7.5)that was experienced in 1999. Liquefaction probabilities (PL) are obtained for each district of the city for whichCPTu data is available with the proposed logistic regression model. Averageliquefaction probabilities of the depth interval 0-6 m and coordinates(Longitude, Latitude) of CPT soundings were plotted to construct a liquefactionprobability map by longitude and latitude. In order to show the effect of depthin liquefaction potential, the obtained liquefaction probability contours werereconstructed by dividing 0-6m depth into three narrow sublayers of 0-2m, 2-4mand 4-6m wherein liquefaction was observed during the earthquake. For eachdepth interval, liquefaction probabilities of the districts are compared withthe observed liquefied and non-liquefied sites in the city after 1999 AdapazarıEarthquake. |
