摘要
为防灾减灾,研究建设项目地质灾害危险性的评估势在必行。以云南省某县的建设项目为例,将GIS技术引入,综合考虑研究区地形地貌、地层岩性、地质构造、工程地质条件、水文地质条件、人类工程活动等有关地质灾害的影响因素,判断评估区地质环境条件复杂程度。在此基础上,分别从地质灾害危险性现状评估、预测评估和综合分区评估逐一论述,将评估区划分为地质灾害危险性大区和地质灾害危险性中等区,并针对拟建项目提出相关的防治措施。得出:评估区现状地质灾害中等发育,工程建设及运营过程中可能加剧、引发和遭受的地质灾害危害性及危险性中等至大,建设用地总体适宜性为基本适宜。
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.
