摘要
本文分析了岩石抗剪参数的不确定性,认为它们是同时包含有随机不确定性和模糊不确定性的随机-模糊变量,提出了依抗剪试验样本值确定岩石抗剪参数的随机-模糊线性回归方法,导出了相应的计算公式,证明了其合理性。算例表明:用随机-模糊线性回归方法处理岩石抗剪试验样本值能获得比传统方法较为合理的结果。
The rock shear strength parameters are considered to be random-fuzzy variables including both random error and fuzzy error. Thcir uncertainties are discussed in this paper. A random-fuzzy linear regression method is presented to determine the rock shear strength parameters on the basis of rock shear tests samples. The corresponding formulae are deduced. The current random linear regresslon method is proved to be a special case of the proposed random-fuzzy linear regression method. In this paper the results obtained from a computing example are given. The recommended method which is more realistic and better than the conventional ones is shown.
