   本文以大量的重載道路資料為主，從實際出發(fā)，結(jié)合理論計算，對重載標準進行了詳細的討論，分別給出了水泥混凝土路面與瀝青混凝土路面的重載標準了；同時，通過大量的水泥混凝土板底應力計算，推導出了混凝土面板荷載與板底應力水平的關系式；給出了水泥混凝土路面與瀝青混凝土路面的交通分級；通過對試驗路各結(jié)構(gòu)層進行承載板測試，發(fā)現(xiàn)現(xiàn)有材料模量較以前有了明顯的提高；對比現(xiàn)場實測的當量回彈模量與理論當量回彈模量，指出現(xiàn)有水泥路面設計中的諾謨圖不能完全符合現(xiàn)有道路材料，從而提出了對理論模量的修正公式。
2. It's difficult to find structure sheaf in a sentence. 用structure sheaf造句挺難的
