Abstract: In this paper, multilayer elastic system and summation method were employed to study the influence of pavement structure on subgrade settlement. The relationships among pavement structure, compressive modulus and subgrade settlement were established and analysed. Finally, measures to prevent subgrade settlement was proposed.

Key words: subgrade settlement, pavement structure, multilayer elastic system

摘要： 采用多层弹性层状体系理论及分层求和法分析了柔性路面不同结构组合对路基沉降量的影 响. 编程计算并得到了路面结构、土基压缩模量与路基沉降量之间的定量关系. 最后提出了降低 路基沉降量的途径.
