|Abstract:||Sand-shredded tire lightweight fills were prepared by blending sands with shredded tire with proper proportions. A laboratory investigation was conducted to study the materials' compression and shear deformation behaviors. A compression-load model was proposed by 1D compression tests. Rebound-reload tests was also conducted to reveal materials' plastic deformation. The materials' shear stress-displacement behavior were studied by direct shear tests. Deviatoric stress-axial strain-volumetric strain curves were observed by triaxial compression tests. Effects of mixing ratios and stress conditions on shear behaviors were also investigated. The efforts made in the paper provides better reference for the reuse of disposed tires in industry. = 通过单向压缩试验,分析了砂-轮胎橡胶颗粒轻质土工填料的压缩变形规律和卸载回弹变形规律,提出了适合该材料的压缩应变-荷载曲线方程.通过直剪试验,研究了砂-轮胎橡胶颗粒轻质土工填料的剪应力-剪位移关系,分析了配比、应力状态等对剪切特性的影响.通过三轴压缩试验,研究了砂-轮胎橡胶颗粒轻质土工填料在不同围压下的偏应力-轴向应变-体积变形关系,分析了配比和应力状态对三轴剪切特性的影响.该研究为废弃轮胎在工程领域的再利用提供了良好的参考.|
