摘要
较详细地分析说明了土层埋深、地下水位对临界标贯击数的影响,澄清了规范公式所带来的上覆应力增加会使土层更易液化的误解。在对规范液化指数分析基础上,重新定义了液化指数。新定义的修正液化指数概念具有明确的概率意义,适用于场地液化评价和风险决策。
The impaction of solum depth and ground water level on critical standard penetration hammer is analyzed in detail, and misapprehensions about that large overburdened effective stress can make sands to liquefy easier are carried. New liquefaction index is presented on the basis of analyzing the liquefaction index of GBJ50011-2001. New liquefaction index has means of obvious probability, and can be applied to the evaluation of site liquefaction and risk decisions.
