Design and implementation of an emergency decision support system for strong earthquakes affecting dams

为提高水库大坝应对强震事件的应急反应能力,减少应急决策的随意性和盲目性,设计并开发一套大坝强震应急决策支持系统。对该系统进行详细的功能需求分析,完成系统整体框架结构的设计,同时对系统的主要功能、系统结构体系、数据库和功能流程等进行深入研究。系统结构的核心包括数据库、模型库、方法库和知识库,采用浏览器/服务器(B/S)架构与客户端/服务器(C/S)架构相结合的模式进行开发,实现了综合信息管理、强震动分析预警、决策支持和应急管理等主要功能。综合信息管理子系统整合了大量有关大坝和地震的信息,为决策提供了丰富的基础数据;强震动分析预警子系统能够实时监测强震信号,对大坝震后可能的危险情况进行预警;决策支持子系统根据预警信息和综合信息,为应急决策提供科学的决策依据;应急管理子系统可以根据决策结果,制定并执行应急响应计划。此外,界面设计简洁直观,易于操作,进一步提升了系统的实用性和用户的使用体验。研究成果可以为大坝强震安全构筑工程安全防护措施外的一道技术防线,有助于降低因大坝强震事件带来的灾害风险,保护水库大坝及下游人民的生命财产安全。

To enhance the emergency response capability of reservoir dams during strong seismic events and reduce randomness and uncertainty in emergency decision-making,an emergency decision support system for dam earthquake response was designed and developed.The system underwent a thorough functional requirements analysis,which informed the design of its overall framework.In-depth studies were conducted on its key functions,structural system,database,and functional processes.The core structure of the system includes a database,model library,methods library,and knowledge base.The system was developed using a hybrid of browser/server(B/S)and client/server(C/S)architectures,facilitating comprehensive information management,seismic analysis and early warning,decision support,and emergency management.The information management subsystem integrates extensive data on dams and earthquakes,providing a solid foundation for decision-making.The seismic analysis subsystem monitors seismic signals in real time,offering early warnings for potential post-earthquake hazards to the dam.The decision support subsystem utilizes warning alerts and comprehensive information to provide a scientific basis for emergency decisions,while the emergency management subsystem devises and implements response plans based on these decisions.Moreover,with its user-friendly interface,the system significantly enhances practicality and user experience.This research contributes to a technical defense system that extends beyond structural safety measures for dam seismic safety,helping to reduce disaster risks from seismic events and protect the lives and properties of people downstream of reservoir dams.
