Dam Safety

目前对灾难性大坝坍塌的关注集中在设计新大坝的安全目标上，以及可能对现有大坝进行改造。数十亿美元岌岌可危，随着时间的推移，发生灾难的风险也在增加。该项目的主要目标是将低概率/高后果事件的建模、风险分析和管理以及经济分析引入大坝安全。这项工作将分为四个任务：任务1)收集和审查大坝失稳数据，任务2)建立大坝运行的经济效益和社会效益模型，任务3)比较风险和大坝安全的风险目标，任务3)评估大坝安全的风险。和任务4)开发一个经济模型，该模型将考虑风险管理备选方案，重点是公众感知和信息，并将调查成本/收益分析。

Current concern with catastrophic dam failures focuses on the safety goals for designing new dams and on possible retrofit of existing dams. Billions of dollars are at stake and with the passage of time the risk of disaster increases. The main objective of this project is to bring modeling of low probability/high consequence event, risk analysis and management, and economic analysis into dam safety. The work will be divided into four tasks as follows: task 1) collect and review dam failure data; task 2) model the economic and social benefits of dam operation; task 3) examine the comparative risks and risk goals for dam safety; and task 4) develop an economic model that will consider risk management alternatives with emphasis on public perception and information, and will investigate cost/benefit analysis.
