Comparison of liquefaction susceptibility assessed by various in-situ test methods

The occurrence and extension of soil liquefaction phenomenon is strongly dependent on both seismic excitation and soil characteristics at site under observation. Within this research, the focus was given to a comparison of methods for assessing soil susceptibility to this phenomenon based on field measurements. The resistance of the soil to liquefaction was obtained by different methods requiring in-situ test results, namely from SPT, CPT, DMT and shear wave velocity measurements. The evaluation of cyclic resistance ratio (CRR) was calculated for data captured at three different locations, including vicinity of Hydro Power Plant Brežice site (Slovenia), oil terminal Porto Romano (Albania) and Çanakkale city (Turkey).
