摘要
采用有限层元和三维等参元复合有限元方法对沥青混凝土与碾压混凝土复合式路面进行了荷载应力、温度翘曲应力分析，系统研究了沥青层厚对复合式路面中碾压混凝土板的荷载应力、温度梯度和疲劳寿命的影响，提出考虑荷载和温度综合作用的碾压混凝土疲劳并指出复合式路面的设计要点。
Load stress and thermal bending Stress of asphalt Concrete and rolled concrete compound Pavement was analysed with finit layer element analysis.The relationships between load stress, temperature and fatigue life the thickness of the asphalt layer and the rolled Concrete were studied, and design keys of compound pavement and fatigue equation of rolled concrete under the action of load and temperature.
