深圳市排水管网数字孪生实现关键路径

Key path implementation of digital twin for Shenzhen drainage networks

摘要:

为解决排水管网动态化、精细化管理难题，以及涉及地面坍塌、水污染等城市公共安全问题，借鉴数字孪生水利工程建设经验，以排水管网为研究对象，分析深圳市管网及信息化建设现状，按照“厂—网—河”流域一体化思维重点，从数据底板建设、模型平台建设及业务场景应用 3 个方面，阐述排水管网数字孪生的具体实现：建立由管网基础、地理空间、监测、业务管理、跨行业共享等数据组成的持续动态更新的孪生数据底板；通过水文水力学模型分析搭建管网静态和动态模型，支撑排水管网评估分析、运行监测预警、雨污系统调度等；建立体现“四预”功能的排水管网数字孪生业务应用。排水管网数字孪生建设可补充智慧城市地下数据资源，实现问题管网诊断、管网规划设计、水污染治理、洪涝预警分析等。

Abstract:

To address the challenges of dynamic and precise management of drainage networks，as well as urbanpublic safety issues such as ground collapse and water pollution，this study draws from the experience of digital twinimplementation in water conservancy projects. Focusing on the drainage networks in Shenzhen，the study assesses thecurrent condition of drainage networks and their information infrastructure. Following the integrated basin approachof “factory-network-river”，it outlines the specifi c implementation of digital twins for drainage networks across threekey aspects：database construction, model platform construction and business scenario application，which expounds theconstruction of a dynamic and continuously updated digital twin data plate encompassing pipe network infrastructure，geographic spatial data，monitoring systems，business management tools，and cross-industry sharing data. Moreover，it highlights the establishment of static and dynamic models for drainage networks through hydrological and hydraulicanalysis，supporting functions such as drainage network evaluation，operation monitoring，early warning systems，and rainwater and sewage system dispatching. Additionally，it emphasizes the development of digital twin businessapplications that reflect the “four pres” functions for drainage networks. The implementation of digital twin fordrainage networks complements the underground data resources of smart cities，facilitating diagnosing problematicpipe networks，planning and designing drainage systems，water pollution control，and flood warning analysis.
