As a new type of building material widely used in engineering fields such as water conservancy, transportation, and construction, the durability of woven geotextile is an important indicator for evaluating its performance and service life. However, environmental factors have a significant impact on the durability of woven geotextile, which is directly related to the safety and long-term benefits of the project.Temperature is one of the key factors affecting the durability of woven geotextile. Under high temperature conditions, geotextile materials may soften, resulting in reduced strength and easy deformation. Especially in hot areas in summer, long-term high temperature exposure will accelerate the aging process of geotextiles and shorten their service life. On the contrary, under low temperature conditions, the flexibility and strength of geotextiles will also be affected, becoming fragile and easy to break. Therefore, it is crucial to choose suitable geotextile materials and take appropriate protective measures under different climatic conditions.Ultraviolet radiation is another influencing factor that cannot be ignored. Direct exposure to ultraviolet rays will cause the aging of geotextile fibers, accelerate their decomposition and embrittlement. Geotextiles exposed to sunlight for a long time will gradually weather their surface fibers and reduce their strength, thus affecting the overall performance of the geotextile. Therefore, in areas with strong ultraviolet rays, geotextile materials with anti-ultraviolet additives should be selected to extend their service life.In addition, the erosion of moisture and chemicals can also have a negative impact on the durability of woven geotextiles. Moisture in a humid environment may penetrate between the fibers of the geotextile, causing fiber expansion and unstable molecular structure, thereby reducing its strength and stability. At the same time, certain chemicals, such as oils, acid and alkali solutions, will corrode the geotextile fibers and accelerate their aging process. Therefore, when using geotextiles in areas containing these chemicals, special attention should be paid to their corrosion resistance.In order to reduce the impact of environmental factors on the durability of woven geotextiles, a series of measures need to be taken. For example, in areas with high temperature and strong ultraviolet rays, geotextile materials with high temperature resistance and anti-ultraviolet rays can be selected; in humid and chemically corrosive environments, geotextile materials with better corrosion resistance should be selected. At the same time, during the construction process, attention should be paid to properly protect the geotextile to avoid unnecessary damage.In summary, environmental factors have an important impact on the durability of woven geotextiles. By rationally selecting materials, taking protective measures, and strengthening construction management, the impact of environmental factors on the durability of geotextiles can be effectively reduced, ensuring their long-term and stable operation.
