摘要
岩石力学参数与岩体力学参数的确定在岩石工程是极其重要的。但岩石的赋存环境存在许多的不确定因素 ,确定它们比较困难。由于岩体赋存条件的复杂性以及地质勘探工作量和实验工作量的限制 ,地质勘探取样存在随机性。实验工作中也不可避免的会产生误差 ,从而产生随机误差。同时岩石工程中对岩石的分类、岩体的分类以及对样本的分组也是人为划分 ,从而岩石样本也存在模糊性。传统的统计方法不适应处理模糊性 ,因此 ,应建立一种既考虑岩石力学参数和岩体力学参数的随机性又考虑它们的模糊性的随机—模糊统计分析模型。
Determination of rock mechanics parameters and rock mass mechanics parameters is extremely important to rock engineering. However, there are many undetermined factors in rock existing environment. Because of the complexity of the rock mass existing condition and the limit of geological exploration work quantity and test work quantity, there is random in geological exploration sampling. There is no escape from occurrence of error, therefore, it produces random error. Meanwhile, the classification of rock, the classification of rock mass and grouping samples is artificial. Therefore, there is fuzziness in samples. Traditional statistical method is not suitable for dealing with fuzziness, we should set up a random-fuzzy statistics analysis model which considers not only the random and the fuzziness of rock mechanics parameters but also the rock mass mechanics parameters. This paper just brings up such a model.
