滑坡灾害易损性可分为两大类型:人口易损性和经济易损性。本文依据现场风险填图对宝塔山景区影响居民生命和财产安全的地质灾害进行了风险源的识别,认为宝塔山景区的风险源主要为潜在的滑坡及崩塌灾害,最大风险处人员伤亡总概率为2.62×10-2.a-1;同时,依据工程地质经验法对风险管理易损性各要素进行了定量评价,认为对宝塔山景区居民来说,100 a以内居民平均每年有最大2.62%伤亡的概率存在。根据国际较通用的风险容许标准,认为目前部分宝塔山居民遭受的风险处于不可接受区,建议加强监测。
Vulnerability of landslide hazards can be divided into two types: population vulnerability and economic vulnerability. Based on the field risk mapping, this paper identifies the risk sources of the geo-hazards affecting the lives and property of residents in the Baota Mountain area. The risk sources of the Baota Mountain area are mainly potential landslides and collapse hazards. The total probability of casualties at the maximum risk is 2.62 × 10-2.a-1. At the same time, based on the engineering geology experience method, the risk management vulnerability of the various elements were evaluated quantitatively, for the residents of Baota Mountain area, residents within 100 a average annual maximum 2.62% casualties The probability exists. According to the internationally accepted standards for risk tolerance, it is considered that some of the current residents of Baota Mountain are in an unacceptable risk area, and it is suggested that monitoring be strengthened.
