高速公路水泥混凝土板块划分与车道布置研究

Study on the cement concrete slab division of the expressway and the lane layout

分析了我国高速公路板块划分和车道布置存在的问题,调查了国内外板块划分和车道宽度,提出了3 m×4 m小板块与"四改六"的车道划分方案,得出该方案可大大降低面板的荷载应力和温度应力,提高路面预估寿命,降低寿命周期内费用的结论。

The author analyzes the problems in the slab division of the expressway and the lane layout in our country, investigates the slab division and the lane width at home and abroad, puts forward the lane division scheme of 3 m×4 m small slab and ＂From 4 to 6 ＂, draws a conclusion that the scheme can greatly reduce the load stress and the temperature stress of the face slab, improve the predicted life of the pavement and reduce the cost in the life cycle.
