摘要： 为揭示废旧轮胎条带加筋边坡的承载特性,确定关键影响因素,开展坡顶竖向荷载作用下废旧轮胎条带加筋边坡承载特性模型试验与数值模拟分析,研究加筋层数、条带长度、间距等因素对边坡承载力、沉降与侧向变形的影响规律。结果表明:相比较自然填土边坡,废旧轮胎条带加筋边坡可有效改善边坡内部应力,增强加筋边坡的侧向约束效应,进而提高边坡的竖向受荷承载能力及边坡稳定性,提高幅度随加筋层数的增多而近似线性增大。随着条带长度的增加,加筋边坡的竖向承载能力得以提高,但当长宽比L/B≥4时,承载能力趋于稳定。废旧轮胎横向及竖向间距对加筋边坡极限承载力具有一定的影响,但提高幅度不显著,设计时可在合理控制范围内取较大间距。研究结果可为废旧轮胎条带在加筋土边坡中的工程应用与设计提供良好的借鉴意义。
