地下围岩稳定分级的灰色关联优化模型

Grey correlation optimal model for stability classification of underground adjoining rocks

根据灰色关联分析原理,从多维空间概念出发,将距离平方和最小扩展为广义加权距离最小,通过求条件极值建立了地下工程围岩稳定分级的灰色关联优化模型,并应用于工程实例中。计算结果表明,地下围岩稳定分级的灰色关联优化模型正确可靠,具有一定的实际使用价值。

According to the principle of grey correlation analysis and multi-dimension spatial concept, a grey correlation optimal model for stability classification of adjoining rocks was established through the extension of minimum distance square to generalized minimtrrn weighted distance. Tne application of the model to practical projects shows that the model is correct and reliable, and it is of certain value of practical use.
