Recent deformation characteristics and mechanism of the Shiliushubao landslide in the Three Gorges Reservoir Area

  • 摘要: 石榴树包滑坡是黄蜡石滑坡群中的一个重要滑坡,一直以来备受瞩目,其持续变形对长江航运及人民生命财产安全造成严重威胁。本文通过对石榴树包滑坡的勘探得到其详细的物质组成及结构,通过近两年的GPS表面位移、地下水位、降雨量等自动化监测数据分析,对该滑坡的变形特征、变形机理进行研究。结果表明:(1)石榴树包滑坡最初以前缘变形为主,现阶段以中后部变形为主。(2)降雨是石榴树包滑坡复活的主要原因,受库水位升降与降雨联合作用使石榴树包滑坡持续变形。前缘变形较小主要是由于前缘渗透性大,水力梯度较小的原因;中后部变形大主要是中后部渗透性小,水力梯度相对较大的原因。(3)降雨对滑坡地下水影响较大,使地下水水力梯度增大可达5~9倍。本研究可为三峡库区滑坡灾害监测预警及防治提供重要参考。
    Abstract: Shiliushubao landslide is an important part of the Huanglashi landslide group, which has attracted much attention for a long time. In this paper, the detailed material composition and structure of the Shiliushubao landslide are obtained by the exploration, and the deformation characteristics and deformation mechanism of the landslide are studied through automatic GPS surface displacement, groundwater level, rainfall monitoring in recent two years. The results show that the front deformation is the main deformation of the Shiliushubao landslide at first, and at present, the deformation of the middle and rear part is the main deformation. Rainfall is the main reason for the reactivation of Shiliushubao landslide, which is continuously deformed by the joint action of reservoir water level rise and fall and rainfall. The small deformation of the leading edge is mainly due to the high permeability of the front edge and the small hydraulic gradient; the large deformation of the middle and rear part is mainly due to the small permeability of the middle and rear part and the relatively large hydraulic gradient. Rainfall has a great influence on the groundwater of landslide, which makes the hydraulic gradient of groundwater increase 5~9 times. This study can provide an important reference for monitoring - early warning and prevention of landslide in the Three Gorges Reservoir area.
