基底挖台阶处理的高填陡坡路堤稳定性分析

Analysis on Stability of High-filled Steep Slope Embankment Treated by Substrate Excavation Steps

在山区道路建设中,经常遇见高填陡坡路堤,对其工程处理措施一般采取沿基底挖台阶处理,虽对其处理有效性已通过大量工程映证,但对其稳定性分析计算模型却不够清晰。以重庆市某主干路形成的高填陡坡路堤为例,探讨基底挖台阶处理后的高填陡坡路堤稳定性分析方法。

In the construction of roads in mountainous areas,the high-filled steep slope embankments are often encountered.The engineering treatment measures are generally taken to excavate the steps along the substrate.Although the effectiveness of this treatment has been proved by a large number of projects,its stability analysis model is not definite.Taking the high-filled steep slope embankment formed by a main trunk road in Chongqing as an example,the stability analysis method of high-filled steep slope embankment after the treatment of substrate excavation steps is discussed.
