以普通水泥混凝土路面为研究对象,结合西北寒旱地区特有的气候特征,运用有限元法分析了不同平面尺寸、不同厚度尺寸的水泥混凝土路面板的温度翘曲应力和汽车荷载应力。经分析,得出了四边自由的路面板荷载应力和温度翘曲应力的尺寸效应规律和服役期内普通水泥混凝土路面的尺寸设计原则,并推荐了不同条件下普通水泥混凝土路面平面尺寸组合。
This paper takes Portland cement concrete pavement as the objective of the research,combining with climate characteristics unique to the Northwest region,the finite element software is used to analyze the temperature stress and wheel load stress of the pavement which has different screen sizes and different thickness.The stress distribution and the design principles of Portland cement concrete pavement are obtained,and plane size combinations in different circumstances of Portland cement concrete pavement is recommended.
