Abstract

One of the important problems in earthquake geotechnical engineering is liquefaction phenomenon that happens in loose saturated granular soils. Liquefaction resistance of soils can be evaluated with using laboratory tests such as cyclic simple shear test, cyclic triaxial tests and cyclic torsional test or field tests for example standard penetration test (SPT), cone penetration test (CPT) and shear wave velocity (Vs). Main aim in this study, comparison results of soils liquefaction potential evaluation in the Barandouz Dam in Urumieh between SPT and CPT tests. In continue, liquefaction potential index (LPI) for both method assessed. In this study, 13 boreholes from Barandouz Dam collected and evaluated. Results of research showed that there is no good agreement between two methods. Also, value of LPI based on CPT is more than SPT.
