Özet

Liquefaction is an important damage potential event after earthquakes. Therefore, liquefaction potential of soil should be estimated correctly to decrease these damages. It has been developed a lot of methods for liquefaction estimation based on semi-empirical simplified procedure. In this study, fuzzy logic soil liquefaction potential determination method was first described and then compared with both field observations and other semi-empirical simplified soil liquefaction determination methods. 250 site observations given in the literature were used in both methods. Soil liquefaction potential was predicted successfully using this both methods for the 220 cases out of 250. It was made comparison using these methods for remaining 30 cases. The fuzzy soil liquefaction assessment with certain probabilities provided the authors involved in the design and construction stages to make a flexible decision. Then fuzzy logic liquefaction determination method is applied on the Sirt bridge case in Afyonkarahisar/Turkey. It was decided to construct a sufficient amount of piles under the Sirt bridge foundation for the purpose of decreasing the effects of a possible soil liquefaction occurrence.
