摘要
为提升国家水安全保障能力,致力于智慧水利建设与数字孪生流域建设,围绕"预报、预演、预警、预案"的"四预"系统,对复杂周边环境大型河口泵闸工程堤坝、基坑和外围堰工程进行科学计算与安全分析.依托智能化模拟、数据库建设以及数字化、智能化、网络化,构建具有"四预"功能的智慧水利系统,实现对风险的早期发现与管理.研究成果包括86组堤坝与基坑工程及43组外围堰工程的子数据库,构成智慧水利的核心,赋能精准地预报、快速地预警、前瞻地预演和细化地预案."四预"体系以天、空、地一体化多元水利感知网为基础,实时与安全模型的科学计算相结合,制定灾害态势的时空阈值,为预警提供先机,为启动预演提供指引,为预案制定提供数据支撑,实现预报的先时筹备、预警的实时战备、预演的全时防备三位一体化预案体系,为水安全管理提供了强有力的技术支持.
Abstract
This study proposes an intelligent water conservancy system that incorporates a'four-pre'approach:forecasting,previewing,early warning,and preplanning.The system aims to enhance national water security by integrating advanced risk management techniques,such as intelligent simulations and database foundations.The'four-pre'functionality of the system enables proactive risk identification,warning dissemination,plan development,and measure implementation.The strategy employed here is proactive and based on 129 safety models,which are divided into sub-databases for embankments,foundation pits,and external cofferdams,serving as the intelligence core.To ensure effective disaster management,forecasting merges data from multi-layered water sensing networks for real-time analysis and alerts.Spatial and temporal disaster thresholds are used to establish early warnings,which are crucial in providing the first line of defense against impending threats.A multi-scenario simulation system can support disaster preparedness by utilizing linked forecasts and continuous rehearsals to inform pre-planning.This integration fosters a comprehensive disaster prevention capability,ensuring readiness through a threefold system of interconnected pre-planning protocols.
