基底挖台阶处理的高填陡坡路堤稳定性分析

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。

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

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.
