公路桥头路基跳车现象是道路中普遍存在的问题 ,目前国内外尚没有非常有效的处理措施 ,虽有大量的相关研究 ,但分析与研究内容多局限于减小地基的附加应力以达到控制沉降差的目的。试图从动力学角度出发 ,对柔性路面路基的桥头路基跳车进行动力分析 ,并针对当前施工中的新技术 -采取聚苯乙烯泡沫塑料工法 (EPS)的隔振性能进行了有限元分析 ,以期能为工程设计与施工提供依据
At present, there is not a very effective treatment measure at home and abroad. Although there are a lot of related studies, the contents of analysis and research are mostly limited to reducing the additional stress in the foundation so as to control the settlement Poor purpose. In this paper, dynamic analysis of bridgehead embankment jumping on flexible pavement is attempted from the point of view of dynamics, and the finite element analysis of vibration isolation performance of polystyrene foam (EPS) For engineering design and construction to provide the basis
