摘要
地下坑道的稳定性一般以坑道周边位移来判别。本文提出用模糊概率分析法代替现行的定值判别法。以模糊统计资料结合专家评判确定稳定性隶属函数;以量测资料的数字特征确定坑道变位的概率密度,从而导出一般公式。通过算例说明模糊概率比定值判别的合理性。
The stability of underground gallery ordinarily distinguished by periphery displacement.This paper presentsasubstitution the of Fuzzy probability analysis for the fixed value distinguishing;according to the statistical datum and specialist discusses ascertains the affiliation function of stability;and ascertains the probability density of gallerys displacement on the basis of measuring numeral feature,then infers a calculate formula.The example explicates the rationality of Fuzzy probability.
