紫外光老化土工膜和土工布的界面剪切特性
Interfacial shear properties of geomembrane and geotextile under ultraviolet aging
摘要
Abstract
To investigate the evolution characteristics of the interface strength of geosynthetics,a large-scale ultraviolet(UV)aging model test chamber was used to conduct aging tests on geomembrane(GMX)and geotextile(GT)for up to 80 days and 40 days,respectively.Periodically collected aged specimens were utilized to perform temperature-controlled direct shear tests on GMX-sand,GT-sand,and GMX-GT interfaces.The influence of UV aging on the shear strength of these three interfaces was quantitatively analyzed.The results show that UV aging has a stronger effect on the shear strength of the GMX interface than on the GT interface.Furthermore,the shear strength of the aged GMX-GT interface exhibits a trend of initial increase followed by a decrease with prolonged UV aging time.关键词
