红层软岩崩解性的灰色关联分析

采用灰色关联度法对红层软岩的粒度分形特征以及矿物、化学成分试验数据与其崩解性进行了关联分析.分析发现,与成分相比,红层软岩的粒度分布分形特征参数与崩解特性具有更高的关联度,表明沉积形成时的环境决定了成岩后的红层软岩崩解性强弱.因为红层软岩中蒙脱石含量少,因此在各种成分中伊利石含量对红层软岩崩解性影响最大,说明水理特性不稳定的矿物含量始终是影响软岩崩解的主要因素.

Grey Correlation Analysis of Slake Durability of Red Bed Weak Rock

Applying the grey correlation methods,this paper analyzed the correlation of slaking durability and granularity fractal characteristics of red bed weak rock as well as the experimental data of mineral and chemical component.The analysis shows that,compared with mineral and chemical component content,the granularity fractal characteristics have higher correlative degrees with slaking durability,which reflects that the deposit environment influences slake durability deeply than other factors.Because of the little content of montmorillonite in the red bed weak rock,the contents of illite show fine correlation with slaking durability of the rock,which indicates that unstable clay minerals always have deep influence on the slake durability of weak rock.
