Abstract :
Site seismic hazard assessment entails the integration of ground shaking, landslide and liquefaction potential. Liquefaction induced damage has highlighted the importance of considering liquefaction in earthquake risk assessment. Discernment of liquefaction vulnerability is a complex and nonlinear procedure that is influenced by model and parameter uncertainty. Inherent uncertainties encountered in the model can be handled with fuzzy based methods, which are capable of incorporating information obtained from expert knowledge and datasets. In this paper, the use of fuzzy template based (FTB) modeling is proposed for assessing earthquake-induced liquefaction. The efficiency of the proposed method is verified using actual liquefaction data reported in the literature. Overall, the correct liquefaction classifications obtained are 98% and 92% for training validation datasets, respectively.
