贵州某高填方边坡稳定性分析与加固处理

Stability Analysis and Reinforcement of a High Embankment in Guizhou Province

高填方边坡高度大、土石方工程量大,边坡稳定性问题十分重要。本文以贵州某高填方边坡工程为例,结合现场变形监测资料,采用数值模拟和极限平衡法,进行了高填方边坡变形机理模拟和稳定性分析,结果表明采用坡率法进行高填方边坡放坡时,宽平台内侧填筑体厚度较小部位为边坡稳定分析的重要部位,应给予足够重视。

With large height and huge volume of fillings, the stability of the high embankment is very important. Taking a high embankment located in Guizhou province as an example, combined with field deformation monito- ring data, the deformation mechanism and stability of the high embankment was studied in detail by nmnerical simulation and limit equilibrium method, with a smaller thickness, the inner side of the wide plalform is rery im- portant in the slope ratio optimization, and should be given enough attention for the stability analysis.
