Statistical uncertainty on assessment of spatial liquefaction resistance

研究成果: Conference contribution

抄録

This paper presents a probabilistic assessment framework of spatial liquefaction resistance with considering the statistical uncertainty. The method based on N value obtained from SPT is adopted to evaluate the liquefaction resistance. A Bayesian approach is used to evaluate the statistical uncertainty occurring in determining the statistical parameters of the modified N (Na) value from observation data. The posterior probability distribution of the statistical parameters of Na is evaluated using the Bayesian approach to inference. A Markov chain Monte Carlo (MCMC) method is adopted to draw the values of the parameters from the target posterior distributions in this study. To illustrate the performance of the proposed approach, an example analysis is conducted based on the statistical parameters of Na inferred with the site investigation data. The influence of the statistical uncertainty on assessing the spatial liquefaction resistance is discussed.
