| 摘 要： | 针对在陡峻山区道路拓宽改造中道路保通要求较高的问题,提出“用半桥-边坡复合路基结构拓宽山区道路的方法”,用钢筋混凝土框架结构强化已有道路路堤,以此为基础用悬臂结构加宽道路.该方法最大的优势是避免了深挖高填且在整个施工过程中保持原有道路畅通.

| Abstract: | As the high standard of keeping mountainous highway smooth,a new method which is called "Widening the mountainous highway with half-bridge and slope base composite embankment structures" was put forward.This method aims at strengthening the original embankment with the reinforced concrete frame.On this basis,the highway could be broadened with cantilever construction.The biggest advantage of this method does not only eliminate high fill and deep cut but also keep a clear traffic in the process of construction. |
