| 摘 要： | 为了探究各项因素对土工格栅老化的影响,运用氙灯耐气候老化实验箱和温度烘箱,完成了一系列的老化实验。然后对老化的土工格栅进行拉伸实验,通过拉伸强度和断裂伸长率的对比,判别土工格栅老化的程度。研究结果表明:温度越高,土工格栅老化的越快。在光照实验中,光作用造成的老化要大于热作用;水分对土工格栅的老化影响很小。

| Abstract: | In order to explore the influence of various factors on the aging of the geogrid,Using xeon lamp weather resistance test chamber and oven,a series of aging experiments are completed.then tensile tests are carried out on the aging geogrid,Through the comparison of tensile strength and elongation at break,To determine the extent of the aging of the geogrid,Research results show that:The higher the temperature, the faster the aging of the geogrid;In the light experiment,The aging caused by the light is greater than the heat;Effect of moisture on geogrid aging is very small. |

| Keywords: | geogrid ?photo-oxidation?aging thermal ageing tensile strength elongation at break |
