Application of Statistics in Comparative Test at Geotechnical Laboratory
-
摘要: 采用统计学的方法,选取定量结果的常用统计量——z比分数、偏倚的估计值和百分相对差对土工试验室开展比对试验(人员比对、仪器比对,试验室间比对)的结果进行综合分析,为在缺乏相关规范的情况下,分析评价岩土体物理力学性质指标的合理性提供一定的参考依据。Abstract: In order to analyze results of geotechnical test in comparison between operatives, apparatuses, and laboratories, select common parameters such as z-score,bias estimation and percentage relative difference based on mathematical statistics, which makes it possible to evaluate reasonability of physical and mechanics properties index of rock and soil, in the case of lacking the relevant specification.
