安龙县位于贵州省西南部,地处扬子陆块与右江造山带的过渡地带。该县境内山地、丘陵地貌发育,地形切割较强烈,地质构造、地层岩性复杂。在自然因素、人为因素的作用下,引发了多种地质灾害,使区内生态地质环境遭受严重破坏,给工农业生产和人民生命财产带来较大的损失和严重危害。本文分析研究了因降雨为主引发的滑坡、崩塌,因岩溶充水矿床疏排地下水所引起的岩溶塌陷,因矿山企业采矿形成的采空区为主引发的采空塌陷等地质灾害发育特征及成因分析。地质环境是一个复杂多变的、不稳定的开放系统,其变化就构成了地质灾害形成与发展的基础与条件。地质灾害的发育、分布、致灾程度与地质环境中的地形地貌、地质构造、岩土体地质类型、水文地质条件等因素及人类工程活动强度有着密切的关系。并针对存在的地质灾害隐患提出防治措施及建议。
Anlong County is located in the southwest of Guizhou Province, is located in the transition zone between the Yangtze block and the Youjiang orogenic belt. The county territory of mountainous and hilly landform, terrain cutting strong, geological structure, stratigraphic lithology complex. Under the influence of natural factors and man-made factors, a variety of geological disasters have been triggered, causing serious damage to the eco-geological environment in the area, causing great losses and serious damages to industrial, agricultural production and people’s lives and property. This paper analyzes the development of landslides and landslides triggered by rainfall, the karst collapse caused by the drainage of groundwater due to karst waterflooding deposits, the development of geological hazards such as the mined-out and collapse caused mainly by the goaf formed by mining enterprises, Causes. Geological environment is a complex and volatile, unstable and open system, and its changes form the basis and conditions for the formation and development of geological disasters. The development, distribution and disaster degree of geological disasters are closely related to such factors as topography and geomorphology, geological structure, geological and geologic types of geotechnical and geological conditions, hydrogeological conditions and intensity of human activities in geological environment. And puts forward prevention measures and suggestions for the existing hidden dangers of geological disasters.
