摘要
文章通过建立平面应变模型,对比分析了车辆荷载作用下有无设置应力吸收层的沥青加铺层结构的裂缝尖端应力和应变场变化情况。结果表明,应力吸收层能有效改善结构裂缝尖端应力和应变场,具有良好的阻裂效果。
Through constructing a plane strain model, the article made a comparative analysis of the crack-Up stress and strain field, change conditions of asphalt overlay structure with or without stress absorption layer under vehicle load effect.It is proved that stress absorption layer has great crack resistance, effectively improving structural crack-tip stress and strain field.
