摘要
Abstract
As lack of research of geocell reinforced rubber-sand mixture (RSM), the direct shear and consolidation deformation experiments are conducted on the reinforced RSM. The reinforced RSMs with rubber mass content of 20%and 30%respectively are studied, and the shear stress-shear strain curve, the vertical displacement-shear displacement curve and the consolidation pressure-settlement curve are obtained. The result indicates that:the strength of RSM is greatly enhanced by the reinforcement of geocell, specifically the cohesive factor is significantly improved and the friction angle is slightly affected. After the reinforcement by geocell, the shear contraction and dilatancy of RSM decrease significantly, as well as the vertical deformation under consolidation reduces obviously. The effect of reinforcement by geocell increases with the mass content of rubber in RSM.关键词
