Abstract

Abstract

To study the reinforcement mechanism and effect of ecological fibers on sandy soil, jute fiber-reinforced sandy soil was taken as the research object. Through a combination of indoor direct shear tests and discrete element numerical simulations, the influence of different jute fiber contents on the shear performance of reinforced sandy soil was analyzed. The research results show that the addition of jute fiber to sand can effectively improve the shear strength of sand. The overall trend is that the cohesion and internal friction angle of sand first increase and then decrease with the increase of fiber content. When the fiber content is 0.4%, the increase in cohesion is the most significant, reaching 20.8 kPa. When the fiber content is 0.2%, the increase in internal friction angle is the largest, with a value of 14.69%. This study provides a reference for the application of ecological fibers in sandy soil filling projects.
