ABSTRACT
As an important geosynthetic material, geotextile is widely used in the fields of water conservancy, harbor and navigation, roads and bridges, etc. The quality of the geotextile is of great concern as a prerequisite for ensuring the safety of the project. To determine the influence of the test environment on the geotextile, the geotextile was tested by changing the state regulation, temperature, and relative humidity during within a certain range. The test results were analyzed using mathematical and statistical methods to obtain discrete characteristics of the test results along with the characteristics of the change in the numerical magnitude with temperature and humidity. The study results show that: the influence of temperature and humidity on the test results is manifested in the change of numerical value and data dispersion (18℃–25℃, 50%–70%), range of temperature and humidity changes, the geotextile unit area mass changes less with temperature and humidity, the coefficient of variation dispersion is smaller; geotextile tensile strength is affected by temperature and humidity changes, the coefficient of variation has a certain dispersion, and the dispersion of elongation is smaller than the tensile strength. The coefficient of variation is affected by changes in temperature and humidity, and increases with temperature.
