N2 - Both the model and parameter uncertainties should be taken into consideration for evaluation of soil liquefaction potential during earthquake. The paper aims to develop a new method to quantify the model uncertainty of the simplified method. The proposed method is constructed by the random simulation technique. The CPT-based liquefied/non-liquefied case histories are collected from documents to determine the Roberson and Wride(1998) model (RW) uncertainty for example. The results show that the RW model uncertainty can be defined by a c1 parameter with an expected value is 1.16 and a coefficient of variance value is 0.12 for all case histories. Finally, results comparison is presented for the validity of the proposed method.
