土性相关距离的自由分布统计研究

Study on Correlation Distance of Soil by Distribution-free Statistical Test Methods

利用自由分布统计检验的方法研究了不同土性参数、不同土层对相关距离值的影响。认为相关距离是土体的属性 ,对同一土层由原位试验参数得出的相关距离值要大于室内指标的结果 ,更能反映土体的真实属性。

The effect of various soilmass and parameters of soil property on the correlation distance is studied by methods of distribution free statistical test. The correlation distance which is a property of soilmass calculated from in situ parameters is thought to be more reliable, and often greater than those calculated from indoor experiments. There may be no statistical difference among the correlation distances resulted from various parameters.
