南京牛首山南侧山体滑坡地质特征及稳定性分析

Geological Characteristics and Stability Analysis of Landslide on the South Side of Nanjing Niushou Mountain

牛首山南侧山体滑坡位于南京牛首山森林公园内,2015年6月发生滑坡后,为保护山脚在建建筑及牛首山景区游客的生命财产安全,相关单位及时开展应急抢险工作,于2016年3月完工。但随后因强降雨,滑坡后缘再次出现新张拉裂缝,经多方专家学者论证,该滑坡需进行详细勘查。论文在详细勘查的基础上,依据钻探、物探及位移监测等资料介绍了滑坡体的结构特征及变形特征,从滑坡的形成条件及诱发因素分析了滑坡成因,对应急抢险前后的滑坡稳定性进行了分析和计算,并提出了防治措施建议,可为该滑坡的下一步综合治理提供参考。

The landslide on the south side of Niushou mountain is located inNanjing Niushoumountainforest park.Afterthe landslide in June2015,in order to protect the construction in progress at the foot of the mountain and the life and property safety of tourists in Niushou mountain scenic area,relevant units timely carried out emergency rescue work,which was completed in March 2016.However,due to heavy rainfall,a new tension crack appears againat the back edge of the landslide.According to the demonstration of many experts and scholars,the landslide needs to be investigated in detail.Based on the detailed exploration,the paper introduces the structural characteristics and deformation characteristics of the landslide mass according to the data of drilling,geophysical exploration and displacement monitoring,analyzes the causes of the landslide from the formation conditions and induced factors of the landslide,analyzes and calculates the stability of the landslide before and after emergency rescue,and puts forward prevention measures and suggestions,which can provide reference for the next comprehensive treatment of the landslide.
