黔西北矿产资源丰富,是省内重要工业基地。该区位处云贵高原东缘,山高谷深。滑坡、崩塌、泥石流时有发生。影响开发建设。通过遥感解译和野外验证共发现滑坡、崩塌、泥石流等地质灾害2360处。主要分布在赫章一威宁金钟一线东南。受多种环境因素综合控制。切割剧烈的地形,陆源碎屑岩或玄武岩分布区,软硬岩层叠覆的地层结构,平缓的招皱构造以及断裂构造发育地段,都是容易发生滑坡、崩塌、泥石流的敏感部位。文中还对古滑坡、高速滑坡、潜在滑坡和地裂缝发展趋势、斜坡变形破坏的时间效应作了讨论,并对滑坡、崩塌、泥石流作了分区评价。
Qianxinbei mineral resources are rich, is an important industrial base in the province. The area is located in the eastern edge of the Yunnan-Guizhou Plateau, deep valleys. Landslides, landslides, debris flows occur from time to time. Affect the development and construction. A total of 2360 geological disasters such as landslides, landslides and landslides were identified by remote sensing interpretation and field verification. Mainly located in Hezhang a Weining Admiralty southeast. Comprehensive control by a variety of environmental factors. Severe terrain, terrigenous clastic or basalt distribution, stratigraphic structure of soft and hard rock overburden, smooth crinkle structure and fault structure development are all susceptible parts of landslide, collapse and debris flow. The article also discusses the time effect of the ancient landslide, high-speed landslide, potential landslides and ground fissures, and the time-effect of slope deformation and damage. The landslide, collapse and debris flow are also evaluated.
