基于RMR对围岩模糊分级参数权重的正交分析

On the orthogonal analysis of the weighting of fuzzy classification parameters of surrounding rock at the basis of RMR

以RMR评分标准为模型构造正交试验,通过数据分析得出围岩参数的权重次序,指出此法为围岩模糊分类的权值确定提供了客观的理论依据,使得围岩模糊分类法更加实用可行。

The orthogonal experiment is made at the basis of RMR assessment criteria,and the weighting order of the parameters of surrounding rock is got through data analysis.It points out that this method provides theoretical foundation to the blur classification of surrounding rock,thus makes fuzzy classification of surrounding rock more practical and applicable.
