滑坡稳定性计算和滑坡稳定性量化评分方法的适用性对比研究——以湖南衡东某风电场公路切坡为例

Comparison of the landslide stability calculation and landslide stability evaluation method:A case of the cutting slope of a wind farm in Hengdong,Hunan

拟以湖南衡东某风电场公路切坡为例,对比分析了公路切坡稳定性评价常用的两种分析方法,即滑坡稳定性计算和滑坡稳定性量化评分,以具体的工程项目为案例,依据公路切坡引发滑坡的地质环境条件,应用两种方法对该切坡可能形成的滑坡进行了对比分析。研究表明:对于勘查程度较高的大型滑坡稳定性评价,采用滑坡稳定性定量计算方法,结论较为准确;对于勘查程度较低的中小型滑坡稳定性评价,采用滑坡稳定性量化评分法,可减少工作量,结论较为准确;对于为大型且地质环境条件复杂,建议用两种方法相互论证,结论可信度高。

This paper takes Hunan Hengdong Wind farm road cutting slope as an example, compared two kinds of commonly used analysis metods for cutting slope stability evaluation, namely , slope stability calculation of landslide stability and quantitative evaluation . To the specific project as a case, on the basis of highway cutting slope landslides caused by the geological conditions, application of the two methods may form the landslide are analyzed. The results suggested that the calculation method of landslide stability is better for the evaluation of cutting slope the stability of large-scale landslide high exploration degree, while , the landslide stability quantitative scoring method is better for small and medium sized, and exploration and evaluation of landslide stability degree, which can reduce the workload and get more accurate conclusion. In terms of the large and complex geological environmental conditions, two methods should be mutually verified, and the conclusion is accurate trusted.
