摘要
地震导致的砂土液化具有很大的随机性。据此 ,提出了评价砂土液化危险性的确定性与不确定性两种方法。确定性方法是以液化指数为变量的多因子判别分析方法 ,不确定性方法是概率分析法 ,即用概率密度函数判断砂土液化灾害的期望损失值。
Sand liquefaction, caused by earthquake is randomness. Thinking of this, this paper provided two effective methods to evaluate its fatality: certainty and uncertainty. The method of certainty uses liquefaction exponent as a variation to differentiate and analyse. Uncertainty is a method of probability analyse which is used for evaluating the expected losses by using probability density function.
