隧道岩石力学参数的随机-模糊统计分析

Random—Fuzzy Statistics Analysis of Rock Mechanics Parameters for Tunnels

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．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，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．

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. Moreover, the errors can not be avoided in the tests, random errors arise. The classification of rock, rock mass and grouping samples are artificial. Therefore there is fuzziness in samples. Traditional statistical method is not suitable for dealing with fuzziness, therefore we should set up a random-fuzzy statistic analysis model that considers the random and the fuzziness of rock mechanics parameters and rock mass mechanics parameters.
