A Comparative Study of the Preliminary Examining Methods for Liquefaction
Potential and Geological Conditions of Coastal Soils in the Southeastern Caspian
Sea
Abstract:
Liquefaction is one of the most common damaging phenomena and its importance has motivated research. Various methods have been recommended by investigators to analyze liquefaction potential, each of which may be used depending on the quantifiable data and geological conditions. In this study, the liquefaction potential of a foundation soil in the city of Bandar Torkaman, situated in Southeastern part of the Caspian Sea (Golestan Province, Iran) was studied using multiple methods. The geological conditions and soil deposition state were assessed in this region and the influence of geological conditions on liquefaction potential was investigated as well. The obtained results show a relatively close correlation between the liquefaction potential and standard penetration test results, relative density and Atterberg limits. Furthermore, the Casagrande test, which is used for the determination of fine-grained soil liquid limits, displayed, to some extent, dynamic soil behavior. There is also a very close relationship between a soil’s Liquid Limit (LL) and the factor of safety derived from the cyclic stress ratio. Finally, from a theoretical point of view, it is possible that soil may meet criteria for possible liquefaction, but it can be influenced by different interrelated geological factors.
