摘要
分析了路面结构在动载作用下的变形特性;研讨了动态模量在路面评价中的应用思想,水泥混凝土路面面层及地基的动态特性和相关动力参数,建立了水泥混凝土路面动态模量与静态模量的对比关系,并提出了水泥混凝土路面各动态模量的评价标准,为工程实际应用提供参考。
In this article, the deformation characters of pavement structure in multi-layer system with (dynamic) loads are analysed, the applications of dynamic modulus、character and parameter of cement (concrete) pavement slab and subgrade discussed and contradistinctive relation between dynamic and static modulus of cement concrete pavement established, and the authors also put forward a dynamic modulus (evaluation) criterion of cement concrete pavement, which provides some references for project practice.
