深路堑高边坡处理是高速公路建设及后续滑坡治理的重点和难点,因此加强深路堑边坡处理显得尤为重要。本文以丹拉高速公路为例,结合该工程深路堑局部滑塌和坍塌段落工点勘探资料揭示的地层情况及边坡稳定性分析验算,提出了深路堑边坡处理有效的设计方案,对山岭重丘区深路堑边坡处理具有重要的现实参考意义。 Deep cutting of high cutting slope is the key point and difficulty of expressway construction and subsequent landslide control. Therefore, it is very important to strengthen deep cutting slope treatment. Taking Dan Expressway as an example, this paper presents an effective design scheme of deep cutting slope based on the stratigraphic conditions and slope stability analysis revealed by the exploration data of local slump and collapse section of the deep-cutting project in this project. Heavy cutting hill area deep cutting slope has important practical significance.
