| 摘 要： | 对地基的液化情况进行定量化判断已是土木工程界的共识。鉴于目前可靠度理论在岩土工程中因其计算复杂而应用受到限制，本文采用柯尔莫哥洛夫（Koлмогоров）检验方法分析标准贯入击数概率分布规律，在此基础上对临界标准贯入击数的概率分布规律进行适当简化，从而给出了一种可利用标准贯入击数进行液化判断的定量化概率方法，进一步结合工程实例进行分析，提出一些有意义的结论。

| Abstract: | It is a common concept to define quantitatively the state of the foundation liquefaction in civil engineering. The application of the theory of probability in geotechnical engineering is limited as its complicated process of calculation at present. On the basis of analyzing the probability distribution law of the blow count of SPT, and the simplifying the probability distribution law of the critical blow count of SPT, the quantitative probability method of defining liquefaction by the blow count of SPT is given. Some useful conclusions and engineering examples are presented. |
