摘　　要：废旧轮胎的黑色污染给环境保护带来了很大的压力,废旧轮胎用于土体改良加固是一种国际推广应用的新方法。在对废旧轮胎和相应填土材料进行物理力学指标测试分析的基础上,对废旧轮胎加固岸堤的效果以及加筋参数的影响进行了分析。结果表明:轮胎条加筋后,岸堤位移峰值明显减小,且加筋层数越多,位移减小越明显;轮胎条加筋对于减少岸堤肩部、临空面底部拉应力有较明显的作用,且随着加筋层数的增加,对拉应力的抑制作用减弱;在轮胎条间距不变的前提下,顶层轮胎条距离岸堤顶部越远,岸堤最大位移量越大,但是对岸堤最大拉应力值有较好的抑制作用。The black pollution of discarded tires put strain on environmental protection.Discarded tires can be used to reinforce soil,which is a new method gained international application.Based on physical and mechanic index analysis of waste tires and backfill soil,the reinforced effect and factors of discarded tires on embankment have been concluded.The results have shown that the peak displacement of the embankment reduces obviously after reinforcement.The more the reinforced layer,the more the displacement reduces obviously.Discarded tire reinforcement has distinct effect on the reduction of tensile stress in the embankment shoulder and the bottom of free surface.The inhibiting effect on tensile stress becomes weak as enhance of reinforced layer.When reinforced spacing is constant,the farther the distance between the first tire layer and the top of the embankment,the bigger the peak displacement of the embankment,which has good inhibiting effect on the peak tensile stress of the embankment.
