SPSS软件在红粘土性质指标统计分析中的应用

Application of SPSS Software in Statistic Analysis of Property Index in Red Clay

应用SPSS软件,结合贵阳市红粘土的测试数据,描述性统计分析其物理力学性质指标特征,探索性统计各个指标的平均值置信区间。用系统聚类法对红粘土的性质指标进行分类,并探求每类内各指标的相关关系。最后应用SPSS软件的制图功能,绘制贵阳市红粘土在塑性图上的位置图,并寻找其特点。统计分析结果符合实际,为该地区的工程实践提供参考,也为统计分析红粘土的物理力学性质指标找到了新的方法。

By applying the SPSS software, combining the test data of red clay in Guiyang, the physical and mechanical properties and index characteristics are statistics analyzed descriptively, and the confidence interval of average value of each index is statistic analyzed exploratorily. The property index of red clay is classified by using hierarchical clustering method, and the relationship of each kind of index is seeked. At last, applying the drawing function of SPSS software, the location plan on the plasticity chart of red clay in Guiyang is drawn, and the feature is searched. The statistic analysis results are conform to the actual results, and it offers the reference for engineering practice in the area, and it also finds new method for the statistic analysis of the physical and mechanical property index in red clay.
