摘要
采用有限元分析法,利用Ansys软件结合薄板理论和弹性地基板理论,建立板单元和连续半空间地基上的破裂后旧混凝土板块群与新加铺沥青混凝土路面的力学模型[1],计算分析加铺沥青混凝土面层厚度、基层强度及旧水泥混凝土路面破裂块度大小对加铺层结构的影响。
This paper uses finite element method.Establish mechanical model of burst old concrete base plate and new asphalt concrete pavement overlay on plate element and continuous half-space foundation combining with thin plate theory and the theory of elastic foundation.Analyze the impact of the thickness of asphalt concrete overlay and the base strength and the size of broken cement concrete pavement block on overlays.
