| 摘 要： | 娄底地区的地质灾害主要有:塌陷、地裂、房裂、滑坡、地震等。对人们生命财产影响最大的是塌陷与滑坡,这些灾害主要是由于工程地质环境不良、加上人类活动触发所致。塌陷主要出现在岩溶发育的断裂带及其附近,尤其是当地下水位降深和排水量增大时。目前,地下采空区、河道及交通道路两侧以及受破坏的陡坡都存在地质灾害隐患。应加强对地质灾害的综合研究,提高抗灾防灾科学技术水平。

| Abstract: | The geologic hazards in Loudi prefecture are mainly surface collapse, surface fracturing, building fracturing, landslide and earthquakes etc, among which the surface collapse and landslide seriously influence the human life and properties. These disasters mainly resulted from poor engineering geologic environment and triggered off by human activities. The surface collapse occurs mainly along and near the karst-developped fault zone, especially when he drop of underground water level and the drainage of underground water increases. At present, there are still hidden dangers. in the underground mining stope, the both sides of river tunnel and traffic road and the damaged cliffs. The synthetical investigation of geologic hazard must be enhanced so as to raise the hazard-controlling level and make better precautions against geologic hazards. |
