土工膜拉伸强度的稳健统计分析

文章介绍了13家实验室参加土工膜拉伸强度检测能力验证的情况,在保证测试样品均匀性的前提下,采用迭代稳健统计技术对各实验室反馈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 this paper, 13 laboratories participating in the testing of the tensile strength of geomembranes are introduced. On the premise of ensuring the uniformity of the test samples, the feedback test results of each laboratory are analyzed by iterative ro-bust statistical technique. The test ability of each laboratory is evaluated according to the Z score.
