Uncertainty Analysis in Liquefaction Potential Assessment
Soil sites are prone to liquefaction during earthquake. For establishment of various important structures, e.g., nuclear power plant, research reactors, etc., potential site need to be evaluated with regard to liquefaction. There are deterministic methods namely empirical and analytical which are available for liquefaction assessment. But uncertainties associated with various input parameters are not considered by these deterministic methods. Near field and far field earthquake affect liquefaction significantly. In the present study, uncertainty analysis is carried out in liquefaction of a soil site for 9 near field and 7 far field earthquakes. Uncertainty parameters, namely mean, standard deviation, and type of distribution which this random variable follows are estimated from 38 borehole data of site. From these uncertainty parameters and observed data, probability of liquefaction for respective bore hole is evaluated by theory of probability. The results obtained from near field and far field earthquake were compared. Probability of liquefaction has been observed to be higher for far field earthquakes in comparison to near field earthquakes.
