山区高速公路建设由于地形地质条件的因素,不可避免地要遭遇路堑高边坡工程技术难题,切方高边坡的稳定又是有效控制高速公路病害产生的关键,因此,山区高速公路建设要重视路堑高边坡的稳定性勘察与评价。以贵州黔西至大方高速公路某段挖方高边坡为例,介绍山区高速公路高边坡稳定性勘察评价方法。
Due to the topographic and geological conditions in mountainous expressway construction, it is inevitable to encounter the technical problems of high slope engineering of cut slope. The stability of cut high slope is the key to effectively control the highway disease. Therefore, the construction of expressway in mountainous area should pay attention to Investigation and Evaluation on the Stability of High Cutting Slope. Taking a section of high cut slope of Qianxi-Dafang expressway in Guizhou Province as an example, the stability survey and evaluation method of high slope of mountain highway is introduced.
