Abstract
Since the surface of the geotextile is unevenness by knit into a fiber, it is difficult to stick the strain gauges on the geotextile directly. So, a method to stick the strain gauges on the geotextile which stuck the vinyl chloride film is popular. This paper is verifying the accuracy of the strain measured by this method. The results of this strain measurement method under the laboratory tensile test and the field tensile test differs by environmental conditions, and the strain measured by this method was smaller than the strain measured by the image analysis under the laboratory tensile test. However, load and strain which were measured by these methods showed linear relation. This paper checked that the strain measured by this method under the same environmental condition could be used for qualitative comparison.
