摘　　要：本文基于应急韧性防灾理念,结合地下基础设施智慧防灾决策需求,提出了一种基于多源数据深度学习的智慧防灾系统框架,建立了基于地下空间火灾事故案例库、防灾专家知识库、多源数据深度学习融合库和灾害救援与恢复联动策略库的功能架构。根据火灾领域知识和历史灾害案例制定防灾标准,对多传感器监测数据运用多尺度方法分析与表达,为深度学习方法奠定数据基础。以多源数据融合预警、智能通风控制和图像识别辅助救援为例,介绍了智慧防灾系统深度学习模型在上海多个服役隧道和运营地下综合体中的应用。结果显示,该模型相比传统方法可提前发出火灾预警,降低运营通风能耗,在火灾紧急通风和人员自救疏散等方面提供辅助决策支持。智慧防灾系统对于突发灾害时地下空间决策支持体系的数字化、信息化和智慧化建设具有重要意义。In light of the concept of resilient emergency disaster prevention and the decision-making requirements of intelligent disaster prevention in tunnels,this paper proposes a framework of intelligent disaster prevention system based on multi-source deep learning algorithm,introduces an architecture of intelligent disaster prevention system and the collaborative method and application cases of each sub-module.According to the knowledge in the field of fire disaster and case histories,disaster prevention standards are formulated,and multi-sensor monitoring data of tunnels are analyzed and presented by multi-scale method,which provides the dataset for the deep learning.Taking multi-source data fusion early warning,intelligent risk control system and image recognition aid rescue as examples,the application of deep learning in intelligent disaster prevention system is introduced.Compared with the traditional tunnel methods,the deep learning-based system can give fire early warning in advance,reduce the energy consumption of operation ventilation,and provide auxiliary decision support in fire emergency ventilation and personnel self-rescue evacuation.The intelligent disaster prevention system is of great significance to the digitization,informatization and intelligent construction of the tunnel decision support system under the sudden-onset disaster.
