| 摘 要： | 运用R因子分析和R型聚类两种多元统计分析方法,对鲁西南地区深埋粘性土的20组样的8个物理力学指标数据进行了分析。利用R因子分析方法,揭示了各指标对鲁西南地区深埋粘性土状态和力学性质的影响关系。利用R型聚类分析方法,研究了深部粘性土各物理力学指标之间的相关性,为进一步从物理力学指标对深埋粘性土的特殊状态和力学特性的研究打下基础。

| Abstract: | By meanings of R factor analysis and R cluster analysis of two multivariable statistical analysis methods, the 8 index data of the 20 groups great overburden clay were analyzed in the southwest regions of Shandong Province. R factor analysis revealed the state and mechanics of great overburden clay, and R cluster analysis showed the correlation between each physical mechanics index of great overburden clay, this establish the basis for the special state and mechanics of great overburden clay from physical mechanics index. |
