地面沉降风险多向性评估体系建立与全量化应用
Establishment and full quantitative application of multidirectional assessment system of land subsidence risk
摘要
Abstract
Land subsidence is a common geological hazard in the world,and it has occurred in more than 100 countries and regions.Based on the risk theory,a multi-directional risk assessment system of land subsidence is established in this paper,which is suitable for slow geological hazards,including hazard and vulnerability assessment.In the selection of assessment indicators,the land subsidence development and urban development are combined to build a multi-directional risk assessment index system,which not only includes the relevant factors of land subsidence,but also covers the urban planning and development.According to the disaster-pregnant geological conditions of land subsidence,susceptibility degree,development degree,prediction rate and terrain elevation of land subsidence are selected as risk assessment factors.Population density,GDP per unit area,the proportion of construction land and the density of major linear projects are selected as vulnerability assessment factors according to the sensitivity of disaster-bearing body to land subsidence disasters and urban development planning.The established assessment method system has been successfully applied to the comprehensive quantitative risk assessment of land subsidence in Shanghai.关键词
