摘要: 基于废旧轮胎良好的抗拉伸、耐老化及界面粗糙等特性,将废旧轮胎切割成条形成加筋条带,并以轮胎衍生集料作为回填材料,形成复合加筋边坡。结合粒子图像测速技术进行模型试验研究,建立数值模型研究不同加筋条件下的边坡力学响应。探讨轮胎条带层数、加筋位置、废旧轮胎集料(tire-derived aggregate, TDA)复合土加筋层厚度与荷载作用位置对边坡承载力的影响,得到加筋效果随加筋布置方式的变化趋势。结果表明,轮胎条带和TDA复合砂土均可起到良好的加筋效果,且复合加筋边坡承载力相比无加筋提高2倍左右。研究结果证实了采用轮胎条带-TDA复合加筋边坡的可行性,为进一步进行废旧轮胎在道路工程中的循环利用研究工作和工程应用提供了基础。
