摘要: Due to its impact on regional groundwater levels, the impoundment of a reservoir is an important consideration for assessing stability surrounding slopes. This study presents method risk assessment and control landslides in regions where levels can be affected by water levels. The illustrated with case Hongzhuang Yanan city, northern Shaanxi province, China. A numerical model was developed using MODFLOW flow fields were calculated different Safety factors then obtained slope analyzed. Moreover, probabilistic analysis performed Monte-Carlo simulation evaluate reliability probability failure. Finally, reasonable level determined according acceptable level, comprehensive mitigation proposed considering control, relocation, drainage measures.
