摘　　要：土工布材料具有价格低、无污染、使用范围广等优势,是常见的工程建设材料。但其耐久性较差,在长期遭受侵蚀、冲刷的环境中适应性较差。为了提升聚丙烯土工布的抗老化特征,使用TiO_(2)水溶胶对土工布进行浸泡处理,通过研究处理后的土工布材料的抗老化特性,该方法可在一定程度上提升土工布的耐久性。通过室内三轴试验,采用土工布加筋处理后,粗颗粒材料的抗剪强度参数有一定提升。经过现场试验段岸坡治理效果表明,采用土工布加筋粗颗粒的方法可用于河道治理工程。Geotextile materials have the advantages of low price,pollution-free,wide range of use and so on.They are common engineering construction materials,but their durability is poor,and their adaptability in the environment of long-term erosion and scouring is poor.In order to improve the anti-aging characteristics of polypropylene geotextile,TiO_(2) hydrosol is used to soak the geotextile.By studying the anti-aging characteristics of treated geotextile materials,this method can improve the durability of geotextile to a certain extent.Through the indoor triaxial test,the shear strength parameters of coarse grained materials have been improved to a certain extent after geotextile reinforcement treatment.After the bank slope treatment effect of the field test section,the method of geotextile reinforcement of coarse grained materials can be used for river regulation works.
