某高速公路古滑坡堆积体稳定性分析及防治措施
摘要:贵州某高速公路路线展布于一古滑坡堆积体上,滑坡堆积体上平台上有一村庄,滑体方量达99.6万m3,该处路线大部分已桥梁方式通过,局部需开挖边坡形成路堑,在公路实施过程中,改变了滑坡的原平衡条件,这将可能危及施工和运营安全。在查明该滑坡地质环境条件、地质结构和变形滑动机理基础上,建立地质结构模型,利用简化Bishop方法分析其稳定性,同时对防治方案提出一定建议。
Abstract:A highway route in Guizhou is located on an ancient landslide deposit. There is a village on the platform of the landslide deposit. The amount of the slide body reaches 996000 m3. Most of the route has been completed in the way of bridge mode, and the slope needs to be excavated locally. During the construction of the road, the original balance conditions of the landslide is changed, which may jeopardize the safety of construction and operation. Based on the identification of the geological environment conditions, geological structure and deformation sliding mechanism of the landslide, a geological structure model is established. Its stability is analyzed by using the simplified Bishop method, and the prevention and control plans are suggested.
