中文摘要:
      在滑坡灾害防治研究方面,探讨其形成演化机理一直是热点问题之一。前人尚未对岐山县宋家尧村滑坡做过具体研究,笔者分析了该滑坡的基本特征,探讨了其形成条件,最后探讨了滑坡的演化机理。结果表明:宋家尧村滑坡处于渭河北岸斜坡带,在古滑坡复活的基础上形成,由老滑坡和新滑坡组成;新、老滑坡均沿古滑带滑动形成,滑坡体以黄土状土为主;老滑坡为自然诱发因素所致,而新滑坡由人类工程活动诱发复活所致,其滑动形成机理是多因素相互耦合综合作用的结果。此滑坡的基本特征与演化机理在渭河北岸地区的黄土滑坡中具有一定的普遍性,可为其防治设计和预警预报提供一定的参考价值。
英文摘要:
      In the field of landslide disaster prevention and control, its formation and evolution mechanism has been one of the hot issues. Previous scholars have not studied the Songjiayao Village landslide in Qishan County. This paper has analyzed the basic characteristics of the landslide, discussed its formation conditions, and finally analyzed the evolution mechanism of the landslide. The results show that the Songjiayao village landslide is located in the slope zone along the Northern Bank of Weihe River, which is formed on the basis of the revival of ancient landslides and consists of old landslides and new landslides. Both new and old landslides slide are developed along the ancient landslides, and the landslide body is mainly loess-like soil. The old landslides are caused by natural factors, while the new landslides are caused by the revival induced by human engineering activities, and these slides are formed by combined action of multi-factor coupling. The basic characteristics and evolution mechanism of this landslide has a certain universality in the loess landslide along the Northern Bank of Weihe River, which can provide a certain reference value for the prevention design and early warning and prediction.
