摘要
指出隧道结构抗力是同时含有随机性和模糊性的随机－模糊变量，提出了实用于这类变量的随机－模糊统计方法，包括随机－模糊均值和方差，以及随机－模糊概率分布的估计等。对应的传统随机方法作为一种特例被包含于其中。
The uncertainties of the tunnel structure resistance are discussed in the paper.Considering the resistance parameter as arandom fuzzy variable,a random fuzzy statistical method is presented to determine the numerical characteristics and probability distribution of the experimental values. The random statistical formula is proved to be a special case of the presented formula. The results obtained show that the recommended mothod is move realistic than the coventionl one.
