随着施工机械设备及现场施工工艺的不断发展，水泥稳定碎石基层施工已由传统的三层施工向两层施工转变，但层间界面的存在仍对道路结构性能有着显著的影响。本文采用有限元分析软件PLAXIS分别对五种工况下(传统三层施工及四种层间位置的两层施工)的水泥稳定碎石基层道路的路表弯沉、沥青层底拉应变和路基层压应变等指标进行分析比较，研究不同工况下水泥稳定碎石基层路用性能。
With the continuous development of construction machinery and equipment and on-site construc-tion technology, the construction of cement stabilized macadam base has changed from traditional three-layer construction to two-layer construction, but the existence of interlayer interface still has a significant impact on road structure performance. In this paper, the finite element analysis software PLAXIS is used to adjust the road surface deflection, asphalt layer bottom strain and road of cement stabilized macadam base road under five working conditions (conventional three-layer construction and two-layer construction of four layers) to study the road performance of cement stabilized macadam base under different working conditions.
