摘要:
采用三维有限元法分析Sampave应力吸收层厚度变化对沥青加铺层结构荷载应力和温度应力分布的影响,发现Sampave应力吸收层能较大幅度地降低加铺层层底的荷载应力和温度应力,对后者降低效果尤为明显,改善了整个沥青面层结构的应力状态,减少加铺层层底应力集中程度,延缓反射裂缝在加铺层中形成,显示其在抗反射裂缝方面的独特作用.计算结果表明:应力吸收层不宜太厚,建议层厚为2.5±0.5 cm较合适.
Abstract:

The three-dimensional finite element method was used to analyze the influence of the thickness change of Sampave stress absorbing layer on the load stress and temperature stress distribution of asphalt plus pavement structure, and it was found that Sampave stress absorbing layer can greatly reduce the load stress and temperature stress at the bottom of the pavement, which has a particularly obvious effect on the latter, improves the stress state of the entire asphalt surface structure, reduces the stress concentration degree of the bottom of the pavement, delays the formation of reflective cracks in the paving layer, and shows its unique role in anti-reflective cracks. The calculation results show that the stress absorbing layer should not be too thick, and the recommended layer thickness is 2.5±0.5 cm.
