  1. Through the research and analysis on the three aspects concerning the base interface of the pavement panel, crack accumulation, expansion in the pavement panel and interaction between spring plates on the road surface as well as its damage on the road fatigue, it is first brought forth that the process of fissures and breakage in the cement concrete pavement can be divided into three stages, i. e. stage of initial crack formation and damage in the bottom of the pavement slab, stage of accumulation, intensifying & expansion in ruptures from load during the time of use and stage of fissures & breakage in the pavement

    通過對路面板底界面開裂、路面板中裂縫積聚、和路面表面車板相互作用及其對路面的影響等三個層面的研究和分析,首次提出水泥混凝土路面的開裂和破過程可以分為三個階段,即路面板底初始傷西南交通大學博士研究生學位論文第11頁和早期裂縫的形成階段、使用期間荷載作用對路面造成的開裂傷累計、加劇和裂縫階段以及路面斷裂破階段。
  2. But, for the reflective cracking of asphalt pavement with half rigid base course and the cracking of the ac overlay above joints ( cracks ) in existing pcc pavement, the results of research show that the fatigue life of ac layer is mainly the life of the crack propagating stage. so the theory and method of fatigue destructive mechanics ( fatigue fracture mechanics and fatigue damage mechanics ) should be used to study and design the pavement structures instead of traditional fatigue mechanics
