摘要
针对砂土地震液化危害具有随机性和不确定性,提出了砂土地震液化危害的概率分析方法,即用概率表示不液化、轻微液化、中等液化和严重液化,并给出了采用Monte Carlo法(蒙托卡罗法)计算液化危害概率的表达式。采用该方法对一算例进行了分析,认为概率分析方法能较清楚地反映液化危害程度。
As the hazard of sand seismic liquefaction is random, a probability method for assessing the hazard is proposed, that is, non-liquefaction, light liquefaction, middle liquefaction, and serious liquefaction are quantified with probability. The expressions to compute the liquefaction hazard probability are also proposed by the method of Monte Carlo. A case is analyzed by the probability method and the result shows that the probability method can be used to quantitatively assess the liquefaction hazard.
