摘要
超载是中国公路上普遍存在的现象 ,而且超载时轮胎接地压力往往表现出非均匀分布特性 ,这将对路面结构产生很不利的影响。采用三维有限元分析方法 ,分析了柔性基层和半刚性基层的沥青路面结构 ,在不同的超载量情形下路面结构应力响应的差异。
The over loading is very prevalent on highway in China,and the tire pressure takes on non-uniform distributed, so it would be very disadvantageous to the pavement structure. A three dimensional finite element analysis method is utilized to analyze the difference of mechanics response under different levels over loadings in asphalt pavement of simi-rigid base layer and flexible base layer.
