摘要: 通过现场试验,分析了在车板相互作用下水泥砼路面板底动应变与路面平整度、车速之间的关系.在此基础 上,进一步分析了路面板底应力与疲劳寿命的关系,认为平整度是水泥砼路面疲劳破坏的重要影响因素之一,为水 泥砼路面设计理论和方法提供依据.

关键词: 平整度, 水泥砼路面, 板底应变, 疲劳寿命

Abstract: Through field test,this paper analyzes the relafiomhip among the dynamic strain in the bottom of the slab、the smoothness and the velocity,which are under the action of coupling among slabs and vehicle.Based on this,the connection between the dynamic strain in the hottom of the slab and the pavememt’s fatigue life has been analyzed.Through above analysis,the paper presents that the smoothness is one of the most important factors of cement concrete pavement’s fatigue failure,And it puts forward some references to the design theories and methods of cement concrete pavement.

Key words: smoothness, ceme nt concrete pavenmnt, dynamic strain in the bottom of the slab, fatigue life
