Probabilistic Analysis for Liquefaction
A comprehensive review of liquefaction case histories was made and an expanded data set was prepared. This report presents the newly compiled field data together with a criterion for liquefaction which is based on the field observations of liquefaction and non-liquefaction. A simple model is given to calculate the probability of liquefaction conditional to the occurrence of a particular seismic event. Applications of the proposed criterion and the probability model are discussed and comparisons are made between the results of this research and those previously published. Specific applications of the proposed method include an evaluation of overall liquefaction risk at a site and estimation of earthquake-generated excess pore pressures. It is concluded that liquefaction analysis procedures, which are invariably based on field observations, include significant uncertainties because of the imperfect nature of the data used. Using the probability model presented herein, proper evaluations of these uncertainties can be made easily.
