road slab meaning in English

路面板

When the load stress and temperature stress of road slabs combine in a disadvantaged state , pavment structures may be distressed when a large axle load loading one time , the fatigue of pavment structures becomes insignificant
当路面板荷载应力与温度应力的组合处于不利状态时,过大轴载的一次作用就可能造成路面结构的破坏,路面结构的抗疲劳性则无从谈起。
Finally , in response to the cavities beneath road slabs , 3d finite element analyses of pavment structures were conducted , the impacts on bearing capacity and life of pavements caused by cavities were analyzed , the reasons of early distresses were revealed ; also , in the aspects of pavement materials and structures , the measures and methods to prevent cavities were explored
最后,针对混凝土路面板板底脱空现象,对路面结构建立三维有限元模型,通过大量的有限元计算,分析了板底脱空对路面板承载力及使用寿命的影响,揭示了路面发生早期损坏的根本原因,并从路面材料和结构设计方面探讨了防止路面板脱空的措施和方法。
