综合危险性指数法在泰山区地质灾害易发区划分中的应用

Application of Synthetic Risk Index Method in Division of Areas Vulnerable to Geo-Hazards in Taishan District

地质灾害易发区划分是进行地质灾害防治的基础工作。针对泰安市泰山区地质灾害分布特点,进行区内地质环境特征和危险性分析以及综合危险性指数(含潜在地质灾害强度指数和现状地质灾害强度指数)计算,对区内地质灾害易发程度进行定量评价,将泰山区划分成地质灾害高易发区、中易发区、低易发区和不易发区等4个等级,为今后开展地质灾害防治提供依据。

The division of areas vulnerable to geo-hazards is the basis work of geo-hazards prevention and management. By the analysis of characteristics of geological environment and geo-hazards in Taishan District, synthetic hazard index method which contains potential geo-hazards index and present geo-hazards index was applied in quantitative division of areas vulnerable to geo-hazards in Taishan District. In this paper, Taishan District was divided into high, medium, low and not-easily vulnerable to geo-hazards areas. And the map drawing the division of areas vulnerable to geo-hazards can provide a basis for decision-making for geo-hazards prevention and management in the future.
