摘　　要：论文针对某电力隧道工程,通过现场检测包括结构损伤、材料强度、配筋情况以及土体空洞区,承载力计算则使用有限元分析软件 MIDAS GTS NX 进行,最后根据损伤程度、结构变形等指标对隧道安全性进行综合评估。结果显示,隧道整体结构安全性较好,但部分区段存在结构损伤,需要进行加固或修复处理。同时,隧道背后土体状况良好,为隧道结构安全提供了保障。定期巡视检查和及时采取加固措施是保障电力隧道安全运行的重要手段,可为相关工程项目提供参考。This article focuses on a certain power tunnel project.Through on-site inspections,including structural damage,material strength,reinforcement situation,and soil void areas,the bearing capacity calculation is carried out using finite element analysis software MIDAS GTS NX.Finally,the safety of the tunnel is evaluated and rated based on indicators such as damage degree and structural deformation.The results show that the overall structural safety of the tunnel is good,but there are structural damages in some sections that need to be reinforced or repaired.At the same time,the soil condition behind the tunnel is good,providing a guarantee for the safety of the tunnel structure.Regular inspections and timely reinforcement measures are important means to ensure the safe operation of power tunnels,which can provide reference for related engineering projects.
