基于GIS的建设项目地质灾害危险性评估
Geo-hazard danger evaluation of construction project based on GIS
摘要
Abstract
For preventing and reducing disasters, research geo-hazard assessment of construction project is imperative. Taking Some county in Yunnan province of construction project as an example, based on an overall consideration of meteorology and hydrology, topography and geomorphology, rock, geological structure, engineering geology condition, hydrology geology condition, human engineering activities etc of the study area. GIS technology was introduced to judge the complexity of geological environmental conditions in evaluation area. On this basis, the article expounded separately from the geo-hazard present situation, estimate and comprehensive regional evaluation, divided evaluation area into large geo-hazard danger area and medium geo-hazard area, and put forward correlative precaution measures for projects awaiting construction. As a conclusion, the present situation of geo-hazard in evaluation area are medium development, the geo-hazards and risk are medium to large, which could be exacerbated, caused and suffered from by the engineering construction and operation process. The collectivity suitability of the land for construction is general basic propriety. Research results can provide technical support for prevention of geo-disasters.关键词
