摘　　要：该文用概率方法研究了土性、地质条件和地震动特性三方面的不确定性对液化判别的影响 ,得到了液化引起的破坏范围与震级的方程和关系曲线 ,提出了关于影响土的液化势的几乎所有重要因素作为自变量而液化值作为变量的完整方程。这种全因素液化分析的的数学模式 。This paper has studied the impact of uncertainty in the aspect of soil condition, geological condition and earthquake factor to liquefaction evaluation with probability method. The equation and relation curve of the damage scope liquefaction aroused and the magnitude were obtained. The full equation was presented of the liquefaction that affects earth of almost, near all important factors of tendency liquefied as independent variable to worth the complete equation as variable. The mathematic pattern of this kind of whole factor analysis has offered a new train of thought for the research of liquefaction phenomenon.
