共振碎石化路面有限元分析及优化设计研究

基于农村公路水泥混凝土路面大修大改浪潮兴起，现从资源可利用化、发展可持续化角度出发，采用有限元ABAQUS建立各路面结构类型模型进行力学分析，探讨共振碎石化路面结构的优势。通过有限元分析验证了共振碎石化路面结构在未来更多农村公路改造中应用的可能性及合理性。另外，采用试验研究的方式，探索了调整水泥掺量、旧料掺量对破碎混凝土板再生的水泥稳定碎石基层强度的影响，确定最佳掺量，优化设计参数。结论表明可广泛用于重、中、轻型交通的农村公路工程。

Study on Finite Element Analysis and Optimal Design of Resonant Crushed Pavement

Based on the rise of overhaul and reconstruction of cement concrete pavements on rural roads, the finite element ABAQUS is used to establish the models of various pavement structure types for the mechanical research from the perspective of available resources and sustainable development. And the advantages of the resonant crushed pavement structure are discussed. The feasibility and rationality of the resonant crushed pavement structure to be applied in the rural road reconstruction in the future are verified through the finite element analysis. In addition, the experiment and studying methods are used to explore the impact of adjusting the cement content and used material content on the strength of recycled cement stabilized macadam base. The best content is determined and the design parameters are optimized. The conclusion shows that it can be used widely on the rural roads of heavy, medium, and light traffics.
