基于地质环境监测数据的轨道交通安全预警研究

针对复杂地质环境条件下的上海轨道交通结构安全问题，建立健全的轨道交通安全监测机制，包括基准网建设和监测、长期监测、监护监测和巡查等。在此基础上提出了改进的模糊层次分析法，建立了轨道交通预警评估体系，开发了上海轨道交通数字化监护管理系统，并应用于轨道交通4号线海伦路站，实现了基于地面沉降、地质环境、收敛等地质环境监测数据的轨道交通安全预警。

The Research of Rail Transit Safety Early Warning Based on Geological Environmental Monitoring Data

According to structure safety of Shanghai rail transit in the complex geological environmental conditions, the monitoring mechanism of structure safety is set up, and it includes four aspects: the building and monitoring of datum net, long-term monito-ring, guardianship monitoring and patrolling.On this basis, the paper proposes the improved fuzzy analytic hierarchy process meth-ods, and develops Shanghai rail transit digitized care management system.Thus the system is used in line 4 Hailun station, rail transit safety early warning is realized based on geological environmental monitoring date that contain land subsidence, geological environ-ment, convergence, etc.
