利用基于剪切波速的砂土液化判别法，本文提出了一种可考虑剪切波速的随机性和液化及液化危害等级的模糊性的液化和液化危害等级的判别法。作者首先讨论了当剪切波速具有随机性时液化的发生概率，进而给出了确定场地液化和危害程度的发生概率。在此基础上，结合液化和液化危害程度（等级）的模糊性，利用模糊事件的概率分析方法，提出了可同时考虑随机性和模糊性的场地液化和液化危害性的发生概率的计算方法。
Based on the sand liquefaction judgment method based on shear wave velocity, this paper proposes a discriminant method that can consider the randomness of shear wave velocity and the fuzzy liquefaction and liquefaction hazard grade of liquefaction and liquefaction hazard grade. The author first discusses the probability of occurrence of liquefaction when the shear wave velocity is random, and then gives the probability of occurrence of liquefaction and hazard. On this basis, combined with the fuzziness of liquefaction and liquefaction degree (level), the probability of liquefaction and liquefaction of the liquefaction site liquefaction and liquefaction is calculated by using the probability analysis method of fuzzy event.
