The significant influencing factors of ε_t and ε_z were further studied by the response surface methodology (RSM), and a correlation model was presented. The analysis results show that intermediate layer thickness, base layer thickness, subbase layer thickness exerted significant influence on ε_t and ε_z, intermediate layer modulus and base layer modulus exerted moderate influence, and ε_t and ε_z were optimized when 16 cm of intermediate layer, 1800 MPa of modulus, 6 cm of base layer thickness, 1200 MPa of modulus, 40 cm of subbase layer thickness were chosen. The test results may provide a reference for future studies of structure optimization of long-life pavement., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null,

articleAbstract=考虑到长寿命沥青路面结构设计参数多、取值范围大等特点，利用力学分析软件研究了各结构层厚度、模量等因素对沥青层底拉应变和路基顶压应变的影响，通过响应面法分析了影响沥青层底拉应变和路基顶压应变的显著因素，并建立了相应的预测模型。结果表明，沥青中间层、基层和底基层厚度对沥青层底拉应变和路基顶压应变影响最为显著，沥青中间层、基层模量对沥青层底拉应变和路基顶压应变有一定影响，且沥青中间层16 cm、模量1800 MPa，基层6 cm、模量1200 MPa，底基层40 cm时，沥青层底拉应变和路基顶压应变综合结果最优。研究结果为长寿命路面结构组合优化提供了一定借鉴和参考。, correspAuthors=null, authorNote=马士宾，副教授，研究方向为路基路面工程，电子信箱：286563105@qq.com, correspAuthorsNote=null,
