| 摘 要： | 阳泉市矿区地质环境复杂,人类活动频繁,存在塌陷、滑坡等地质灾害隐患。本文在充分调查地质灾害的基础上,构建了矿区风险评价体系,运用信息量法和层次分析法,选取了交通、居民地、矿山等8项指标开展易发性区划;在易发性评价的基础上叠加降雨因子,实现了矿区地质灾害的危险性评价;采用人口、建筑、交通因素构建了承载体易损性模型;并结合危险性和易损性构建了矿区的地质灾害风险评价模型。研究结果表明,矿区中地质灾害高风险地带主要分布在存在矿山活动的赛鱼、蔡洼街道且靠近人口聚集的地方,其影响范围较大,应及时采取监测预报等措施。

| Abstract: | There are hidden dangers of geological disasters such as collapes and landslide in mining area of Yangquan city because of complex geological environment and strong hunman activity. In this paper, the risk assessment system is constructed in mining area based on the full investigation of geological disasters. Selects eight indexs such as traffic, residential, mining to carry out susceptibility zoning using the method of information value and analytic hierarchy process. On the basic of susceptibility assessment, rainfall factors are super imposed to realize the hazard assessment. Selects population, building and traffic factors to carry out vulnerability model. Based on the outcome of hazard assessment and vulnerability assessment, it establishes risk assessment modes. The research shows that medium-high risk areas are mainly distributed in the streets of Saiyu and Caiwa where there are mining activities and close to the population gathering, and the impact range is large. It is urgent to take measure to monitor and warn. |
