摘　　要：黄土—砂泥岩接触面滑坡在陕西地区广泛分布,对输电线路工程造成很大影响。从形态特征、滑体及滑床的物质结构特征、滑面(带)特征等几方面分析该类型滑坡的基本特征,同时对该类型滑坡的主要影响因素展开讨论,分析总结出该类型滑坡具有低速滑动性、反复性、隐蔽性等变形特征。结合输电线路工程实例以及勘测工作特点,提出塔位选择的相关建议。Loess sand mudstone interface landslide has been widely released in Shaanxi Region,which has a great impact on transmission line engineering.In this paper,the basic characteristics of this type of landslide are analyzed from the aspects of morphological characteristics,material structure characteristics of sliding mass and sliding bed and sliding surface(zone)characteristics.At the same time,the main influencing factors of this type of landslide are discussed.The deformation characteristics of this type of landslide,such as low-speed sliding,repeatability and concealment,are analyzed and summarized.Finally,combined with the example of transmission line engineering and the characteristics of engineering survey,the relevant suggestions on the selection of tower location in this area are given.
