摘 要: | 抚顺市西露天矿北帮南阳路路面出现多条裂缝,严重影响交通安全。为此,首先根据现场实际调查及地质钻探资料,对西露天矿北帮地质环境特征进行研究,分析地形条件、大气降水及生活污水入渗对边坡稳定性的影响;其次结合路面变形及建筑物变形规律,研究南阳路滑坡的变形特性;最后使用简布法与毕肖普法对地表变形严重的I-I'剖面进行了稳定性评价,并运用层次分析模型量化滑坡各影响因素的权值向量,引入到模糊综合评价法进行了整体稳定性分析,从而对滑坡稳定性做出综合评价。结果表明:抚顺市南阳路滑坡处于不稳定状态。

Deformation Characteristics and Stability Evaluation of Nanyanglu Landslide in Fushun City |
| |
Abstract: | There are cracks on the pavement of Nanyang Road in the northern slope of Western Open-pit Mine in Fushun city, which seriously endangers the transportation thereon. Thus, this paper, first, according to the data from field survey and geological drilling, studied the geological environment characteristics thereof and analyzed the effects of the terrain conditions, atmospheric precipitation and sewage infiltration on the slope stability second, combining with the deformation rules of the pavement and the structures, studied the deformation characteristics of the landslide along Nanyang Road last, carried out comprehensive evaluation of slope stability in such manner that the stability of the Ⅰ-Ⅰ’ section subject to serious surface deformation was evaluated by Janbu and Bishop methods, and the weight vector of each factor affecting the landslide was quantified by analytic hierarchy process, then by introducing fuzzy comprehensive evaluation method, the overall evaluation was made. The results show that the landslide along Nanang Road is in an unstable state. |
