摘　　要：针对废旧轮胎资源化循环利用问题,提出由废旧轮胎、回填料、基础和地基组成的轮胎墙结构,代替传统的钢筋混凝土面板挡土墙。目前,国内外没有关于废旧轮胎挡土墙的研究,为了使废旧轮胎墙结构在挡土工程中合理化应用,通过FLAC3D建立废旧轮胎挡土墙结构数值计算模型。用实体单元模拟废旧轮胎,考虑轮胎回填料间的接触面单元;分析了废旧轮胎的半径和断面宽度对轮胎墙水平变形的影响,为各影响因素提出了合理的取值范围,可为废旧轮胎挡土墙的应用和推广提供设计依据。In order to recycle waste tires,the tire wall structure,which consists of waste tire,backfill and foundation,is proposed to replace the traditional reinforced concrete face retaining wall.However,there is little research on the waste tire wall.In order to rationalize the application of waste tire wall structure in retaining engineering,the numerical model of waste tire retaining wall structure was established by FLAC3D.The solid elements were used to simulate the waste tires,and the interfaces between tires and backfill were considered.The effects of section width and tire radius on the horizontal deformation of waste tire retaining wall were analyzed,and the reasonable ranges of values for influence factors were put forward.This study can provide basis for the design and application of waste tire retaining walls.
