| Abstract: | The trapezoidal tearing strength of the geotextile was been measured according to the Chinese standards ＂Determination of geotextile trapezoidal tearing strength＂. The evaluation of uncertainty in measurement on trapezoidal tearing strength of the geotextile was made with the national measurement standards＂ Evaluation and expression of uncertainty in measurement＂. Reasons which cause the uncertainty of measurement were analyzed and quantified with mathematical statistics such as variance analysis, and finally the expanded uncertainty was obtained. |
