摘要
应用土工格室加固路基,施工简便效果好,但目前对土工格室加筋土的力学特性及作用机理尚缺乏系统的认识,对土工格室加筋路基的应用技术也研究较少。基于土工格室材料特性及加筋路基的作用机理,探讨了土工格室加筋垫层与软弱地基接触面之间剪应力的作用效应,并对土工格室加筋路基的应用技术进行了讨论。
Geogrid is simple and has good effect for reinforcement of subgrade.However,the mechanical property and action mechanism of geogrid reinforced soil have not been understood systematically and the application of geogrid reinforced subgrade is rarely studied at present.In this paper,based on the characteristics of geogrid material and the action mechanism of reinforced subgrade,the effect of shearing strength between geogrid reinforced cushion and soft foundation is discussed.The application technology of geogrid reinforced subgrade is also discussed.
