| 摘 要： | 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。

| Abstract: | In this paper, we treat emphatically the shear wave velocity-based evaluation method, which is simple to handle and perspective in further application in probabilistic and fuzzy way. We present also the formulae for the evaluation of liquefaction probability and fuzzy probability at given depths, and for a fuzzy evaluation of liquefaction hazard of the total soil layers. A probabilistic liquefaction index and a fuzzy-probabilistic liquefaction index are tentatively suggested to show approximately the liquefaction hazard of soil layer in an indeterminat way. |
