Abstract
Using mathematical statistics, we analyzed the influence of temperature and relative humidity during test on the results. The test data of geomembrane were obtained by changing the temperature and relative humidity ranging from 18°C to 25°C and from 50% to 70% respectively. The results show that under different temperature and humidity, the coefficient of variation of the maximum tensile test value is 8.0%∼17.4%, and the coefficient of variation of average value is 6.7%, which is poor in stability; the coefficient of variation of the test value of elongation at break is 4.7% ∼ 11.7%, and the coefficient of variation of average value is 4.6%, and the value increases with increasing temperature; the coefficient of variation of right angle tear strength is 6.0% ∼ 20.7%, and the coefficient of variation of average value is 6.4%; the coefficient of variation of puncture strength test value is 4.2% ∼ 7.3%, and the coefficient of variation of average value is 6.1%, and the value decreases with the increase of temperature. These results will shed light on analyzing the influence of temperature and humidity on the mechanical test results of geomembrane and determining a reasonable temperature and humidity control range for geomembrane testing.
