青银高速公路旧关至太原段张靖村东滑坡特征及稳定性评价

Characteristics and Stability Evaluation of the East landslide in Zhangjing Village from Guiguan to Taiyuan section of Qingyin Expressway

张靖村东滑坡为一处古滑坡,后因前缘人类活动造成局部复活。本文在对场地工程地质条件和滑坡基本特征进行分析的基础上,判定该滑坡现状处于基本稳定状态,通过验算滑坡坡稳定性及滑动推力,该处斜坡稳定性稍差,增强坡体稳定性后予以通过。研究结果为滑坡的防治、线路工程设计及防灾减灾提供重要地质依据。

The east landslide in Zhangjing Village is an ancient landslide,which was partially revived due to human activities at the leading edge.On the basis of the analysis of the site engineering geological conditions and the basic characteristics of the landslide,we determine that the current situation of the landslide is in a basically stable state.By checking the stability of the landslide slope and the sliding thrust,the stability of the slope is slightly worse,and the stability of the slope body is passed.The results provide important geological basis for landslide prevention and control,line engineering design and disaster prevention and mitigation.
