从裂缝入手分析滑坡成因

Analysis of Landslide Formation from the Cracks

从裂缝的位置、形状等变形特征入手,研究裂缝的发展及其类别,分析了裂缝与滑坡的成因,探究了两者的内在联系。结果表明,地质、降水及引水隧道自身、地表下沉牵引等因素是裂缝产生的原因;青峰断裂的影响、复杂的地形、工程地质条件、引水渠道的渗流,以及持续强降雨等因素是滑坡产生的主要因素,裂缝的类型和发展是影响滑坡稳定的重要因素。

From some deformation characteristics, such as the location or shape of the cracks, the de- velopment and the categories of the cracks are researched, the cause of the crack and landslide are ana- lyzed, and the internal relationship between the both is explored. The results show that the factors, such as the geology, precipitation, water diversion tunnel itself, and surface subsidence traction are the causes of the cracks, while Qingfeng-Fault impact, complex terrain, engineering geological condi- tions, water diversion channel seepage and continuous heavy rainfall are the main factors that result in the development of the landslide. The development and the categories of the cracks are the key factors that affect the stability of the landslide.
