摘要
文章依据《测量不确定度评定与表示》(JJF1059.1-2012)的方法,通过建立数学模型和分析不确定度来源,对高密度聚乙烯(HDPE)土工膜拉伸性能的测量结果进行了评定,并对评定结果进行了讨论。HDPE土工膜拉伸强度和断裂伸长率的不确定度分别为1.6 MPa和38%,该不确定度主要来源于重复性测量。
According to the methods of ＂Evaluation and Expression of Uncertainty in Measurement＂ （ JJ FI059.1-2012 ） , the uncertainty of the tensile properties of high-density polyethylene （HDPE） geomembrane was evaluated by mathematical modeling and analyzing the sources. The tensile strength and tensile strain uncertainty of HDPE geomembrane was 1.6 MPa and 38% respectively, which was mainly from repeatability of measurement.
