摘　　要：随着交通基础设施建设持续扩大,大量隧道进入养护维修高峰期,结构安全风险呈滚动式周期性爆发趋势。目前隧道结构健康监测信息化和智能化程度较低,安全性能感知困难,严重影响了隧道的正常运维。本文立足于隧道结构健康监测和决策需求,提出了一种基于数物交互和数据融合的隧道结构安全性能感知体系框架。首先对隧道结构受力状态感知技术及其误差传播规律进行分析,并采用数物空间交互试验对支护结构各构件相互力学关系进行研究,并基于此建立多源数据各监测量之间的数学模型,对隧道整体结构和各构件的安全性能进行评估。结构安全感知体系可为隧道安全防灾和运维管理提供决策依据,对提高隧道工程现代化、信息化、智慧化管理水平具有重要意义。With the continuous development of transportation infrastructure building,a large number of tunnels have entered the peak period of maintenance and repair,and structural safety threats are bursting on a regular basis.However,the present level of information and intelligence of tunnel structural health monitoring is inadequate,making it difficult to detect safety performance,which has a negative impact on the tunnel's regular operation and maintenance.According to the tunnel structure health monitoring and decision-making demands,this study presents a framework for tunnel structure safety performance perception system based on numerical-physical coupling method and data fusion.First,the tunnel structure force state perception technology and sensor error propagation law are explored,and the numerical-physical coupling test is used to examine the mutual mechanical relationship of each element of the support structure.Then,the mathematical model and data fusion platform between each monitoring quantity of multivariate data are established.Finally,the overall tunnel structure and each component's safety performance was assessed.The structural safety performance perception system can serve as a foundation for decision making in tunnel disasters prevention and operation management,meanwhile,it is critical to enhance the degree of modernization,informatization and intelligent tunnel engineering management.
