摘　　要：从高速铁路大跨度桥梁运营养护需求出发,结合大跨度桥梁的结构特点,采用自动化监测与电子化人工巡检相结合的运营监测系统。监测系统包括自动化监测、电子化人工巡检、数据分析处理及数据管理。监测内容包括桥址环境、外部荷载、结构响应、动力特性、特殊设备和结构表观病害。对监测数据采用统计分析、趋势分析、特征值提取、相关分析、回归分析等分析方法,从而掌握大跨度桥梁在运营阶段的力学行为,提供桥梁养护管理决策。监测系统具有实时在线信息查询、统计报表等功能。本文提出的监测系统设计方案已应用于京沪高铁南京大胜关长江大桥和石郑铁路客运专线郑州黄河公铁两用桥的运营监测,减少了人工检测的工作量,为养护管理人员提供了大量的监测数据。A combination of automatic operation monitoring system and electronic manual inspection are applied in high speed railway large span bridge for its operation and maintenance. The system is consist of 4 sub-systems including automatic monitoring, electronic manual inspection, data analysis processing and data management. Monitoring system includes site environment, external loads, structural response, dynamic characteristics, special devices and visual damages. Statistical analysis, trend analysis, feature extraction, correlation analysis and regression analysis are performed. The behavior of large span bridge in-service is studied, helping bridge maintenance and management decisions. The system has real-time online monitoring system information, statistical reports and other features. The proposed monitoring system design scheme has been applied to operation monitoring of Nanjing Dashenggnan Yangtze River Bridge in the Beijing-Shanghai high speed railway and Zhengzhou Yellow River highway-railway dual-purpose bridge in the Shizheng passenger dedicated line. This system reduces the workload of manual testing and provides scientific data for maintenance management.
