Shear Comparison of Waste Tyres and Biaxial/Triaxial Geogrid Reinforced Soil
摘要
Abstract
Waste tyres reinforced soil is applied for the geotechnical engineering, which the principle is similar to geosynthetic materials. Through large direct shear test, some conclusions could be obtained that interface friction coefficient ratio of several reinforcement materials was less than 1. Interface friction coefficient ratio of waste tyres was 0. 98, which was the closest to soil. Reinforcement effect of several reinforcement materials was great and shear strength significantly increased. The friction angle changed a little, but the cohesion force increased greatly. Cohesion growth of waste tyres, biaxial/triaxial geogrid reinforced soil were 24%, 36% and 60% respectively. Reinforcement effect coefficient of several reinforcement materials decreased with the increasing of the vertical pressure, but compared with the biaxial/triaxial geogrid, reinforcement effect coefficient of waste tyres was less influenced by the vertical pressure change. Therefore, when the case of the vertical pressure change is bigger, the waste tyres are better used as the reinforced material.关键词
