摘要
针对深埋长大隧洞工程全生命期数字孪生建设研究较少的现状,以引江补汉工程为例,构建信息化基础设施、数字孪生平台、业务应用,以及网络安全、保障体系“三横两纵”的全生命期数字孪生引江补汉工程总体架构,探讨多源异构数据融合治理、BIM模型动态更新与场景加载、多场景多目标嵌套模拟仿真等技术难点与解决思路,设计以提升不良地质风险识别与管控、隧洞动态支护、施工仿真与资源配置优化、工程安全分析预警“四预”能力为核心的工程全生命期孪生应用场景与功能,指导后续项目实施,并为类似工程提供借鉴。
In view of few studies on the construction of digital twin in the lifecycle of deep buried long and large tunnel projects,taking the River Diversion Project from the Yangtze River to the Hanjiang River as a case,a“three horizontal and two vertical”overall architecture of the lifecycle digital twin project is built,including information infrastructure,digital twin platform,application,network security,and security system.This paper discusses technical difficulties and solutions of multi-source heterogeneous data fusion governance,BIM model dynamic update and scenario loading,multi-scene and multi-target nesting simulation technology.Twin application scenarios and functions are designed for project lifecycle,with the core of improving the“four pre”capabilities of adverse geological risk identification and control,tunnel dynamic support,construction simulation and resource allocation optimization,engineering safety analysis and warning,so as to guide the follow-up implementation and provide reference for similar projects.
