Abstract
In the existing design codes/standards on the evaluation of liquefaction potential, the uncertainty of soil properties and the expected loss are not taken into account. This paper proposes a new procedure for risk analysis to evaluate the potential risk of liquefaction quantitatively. Monte Carlo simulation is introduced in the proposed method to assess the uncertainty of soil properties. Risk analysis is made as a case study for a model liquefiable ground on the basis of the methods stated in the seven different design codes/standards in Japan. The result indicated that the new method enables to evaluate the probability of liquefaction and anticipated loss by constituting the hazard curve, fragility curve and risk curve.
