地铁盾构隧道结构安全评判指标体系及模型建设研究

本文基于对地铁盾构隧道结构各类病害及变形破坏特征分析，同时结合长期变形及专项维保监测相关工程实践资料，对地铁隧道结构的综合安全性态评判技术及对应评判模型建设开展研究，并结合某地铁区间工程实例，从隧道结构变形监测成果、病害检测成果、结构形变理论极限指标、病害综合评估等多个维度，初步建立了一套较为全面的地铁隧道结构安全评判指标体系及评判模型，可为进一步开展相关隧道病害综合治理及其整体安全管控工作提供技术参考。

Establishment of a Safety Assessment Index System and Model for Shield Tunnels

In this study, the integral security assessment for a subway shield tunnel structure is performed based on the characteristic statistical data analysis of subway structure defects and deformation failure and long-time deformation monitoring data of the subway structure. In addition, a comprehensive safety assessment index system is established based on the dimensions of project experience, literature investigation, deformation limit value, inspection results, elastic limit, and structure disease assessment. The research results provide reference for subway structure disease management and assessment of service conditions.
