周家坪滑坡体位于拟建的官地水电站库尾,系盐源县梅子坪乡政府集镇所在地,水库蓄水后,滑体前缘将被部分淹没,由于其结构松散,可能会影响滑坡体的稳定性,进而影响梅子坪集镇196余人的生命及财产的安全。本文在现场地质调查、勘探及试验成果的基础上,对周家坪滑坡体进行坡体结构和成因分析,并对滑坡体在天然和水库正常蓄水条件下的稳定性进行了系统分析。
Zhoujiaping landslide is located in the Meiziping town in Yanyuan county, which is the site for Guandi Hydroelectric Power Station which will be built in the future. After water is storaged in the reservoir, the front of the landslide will be partly submerged because of the loose structure. The front part of the reservoir banks will be recycled, and it may affect the stability of the landslide, which will affect more than 196 lives and their property. On the basis of field geological investigation, exploration and test analysis, it analyses the slope structure and the forming causes by calculating the stability under two different conditions: natural and filled with water.
