摘　　要：经调查发现由于路缘石破坏而引起公路路面病害现象较为严重.结合有限元软件MSC.NASTRAN进行线弹性有限元分析,模拟计算了公路路缘石在各种不同状态下的受力和变形情况,并基于分析结果简要提出几项路缘石病害防治措施,以作为公路路缘石设计和施工的参考.It is a serious situation that broken curbs result in bad pavement through investigations.Finite element program MSC.NASTRAN software package was employed to analyze the structural responses of curbs on low volume rural roads in different conditions.Several methods are proposed to decrease pavement damage caused by curbs,to provide the reference for curb design and construction.
