摘　　要：为克服堤防决口模拟中静态或单一灾害演化、多因素动态交互影响缺失以及灾害演化、应急决策响应与救援力量调度综合模拟等方面的不足,提出1种基于流固耦合模型和多智能体系统的堤防决口救援联动仿真框架。该框架采用浅水方程模型模拟决口洪水动态漫延过程,耦合泥沙悬浮搬运模型定量解析水流对堤坝的侵蚀与沉积机制,同时引入多智能体系统构建“灾害演化—救援调度—应急决策”动态交互模型,实现多因素耦合下的应急决策推演,并以2024年洞庭湖团洲垸堤防决口事件为案例进行实例验证。研究结果表明:该框架能够有效模拟决口扩展及救援过程,预测灾害演化趋势,生成救援处置建议,可为堤防决口应急响应提供参考。To address the limitations in current dike breach simulation,such as the static/single-disaster evolution,the insufficient multi-factor dynamic interactions,and the lack of integrated simulation for disaster evolution,emergency decision-making and response,and rescue force deployment,a simulation framework for the emergency rescue collaboration of dike breach based on the fluid-solid coupling model and multi-agent system was proposed.The shallow water equations model was used to simulate the dynamic propagation process of breach flood,and it was coupled with the sediment suspension-transport model to quantitatively analyze the erosion and deposition mechanism of water flow on dike.Meanwhile,the multi-agent system was introduced to establish a dynamic interaction model integrating“disaster evolution-rescue allocation-emergency decision-making”,realizing the emergency decision deduction under multi-factor coupling.A case verification of dike breach in Tuanzhou polder of Dongting Lake in 2024 was carried out.The results show that the framework can effectively simulate the breach expansion and rescue process,predict the evolution trend of disaster,and generate the rescue disposal suggestions,which can provide reference for the emergency response of dike breach.
