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。
In order to analyze results of geotechnical test in comparison between operatives, apparatuses, and laborato- ries, select common parameters such as z-score,bias estimation and percentage relative difference based on mathematical statis- tics, 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.
