Determination of liquefaction potential of soil by using standard penetration test (Spt) in Edirne province and districts

One of the most important causes of damages after the earthquake is the liquefaction of the ground, which occurs under repeated and transient loads oncohesionless and watery saturated sandy or silty soils. This study includes evaluation of the liquefaction potential of Edirne province and its surroundings. It is thought that Edirne Province may also be affected in an earthquake that may occur at the North Anatolian Fault Line or a possible earthquake around surroundings of Edirne. Therefore, the liquefaction potential of Edirne province have been investigated using standard penetration tests (SPT) and relevant laboratory data. A total number of 77 borehole were opened in Edirne province and districts, followed by standard penetration tests (SPT) to obtain desired characteristics. Remolded and undisturbed soil samples were extracted from boreholes and corresponding experiments were conducted to obtain physical and mechanical properties of the soil. Methods used for analysis of liquefaction potential have been carried out by researchers like Seed and Idriss (1971), Youd (2001), Rouch (1998), Wang (1979) and Dorby et al.(1992). Since the work of Idriss & Boulanger in 2008-2010 was not included in previous studies, this publication was taken as a pioneer and the LiqSVs program using this method was used for analysis.In the last phase of the study, different earthquake magnitude scenarios are being considered and how the potential of liquefaction will be affected with increasing seismic activity and depth of focus is presented.
