稳健统计技术在土工格栅拉伸强度检测能力验证中的应用

Application of Robust Statistical Techniques in Verification of Tensile Strength Testing Ability of Geogrid

本文介绍了17家实验室参加土工格栅拉伸强度检测能力验证活动的情况,检验了测试样品的均匀性,采用迭代稳健统计技术,对各实验室所得的试验结果进行了分析,根据Z比分数值对各实验室检测能力进行了评价。

In the paper, the condition of 17 laboratories participating in verification geogrid is introduced. The uniformity of test samples is verified. Iterative robust statistical techniques are adopted foranalyzing the test results obtained from all laboratories. The testing ability of all laboratories is evaluated according to Ascore values.
