摘要
在高等级公路的建设中 ,线形要求严格 ,在山区及丘陵地区往往需要采用开挖和填方等方式通过 ,新滑坡的产生以及老滑坡的复活可能性大增。本文以绵广路 K2 0 0 + 70 0～ K2 0 1 + 0 0 0段一古滑坡为例 ,详尽讨论了其在公路施工影响下复活产生了新的多级滑坡的工程地质条件 ,并分析评价了滑坡的稳定性、提出相关的工程处理措施。
Engineering excavating and filling are often used in highways construction at mountainous area. It is easy to lead new landslides and reliving old landslides because of the south-west of china. As an example, this paper introduces an old landslide located at K200+700～K201+000 of Mianyang-Guanyuan highway. The engineering geological conditions, which control reliving of old landslide and forming new landslides because of highways construction, is discussed in detail. It is Emphasized that we must pay attention to the geologic advance forecast in engineering construction.
