摘　　要：根据中、下承式拱桥的结构特点,提出桥梁健康监测流程与健康档案概念,并分析桥梁健康监测健康档案的指标构成和特点。在进行桥梁健康监测时,先建立桥梁的基准模型和健康档案,确定检查对象和观测指标后,根据监测流程进行现场测量,并比较各指标测量值与健康档案中参考值的大小,根据比较结果分析构件的工作状态。以京港澳高速刘江大桥为例,说明中、下承式拱桥的健康状态评估的实现,现场监测结果显示该时间段京港澳高速刘江大桥第4跨健康状况良好。According to the structure characteristics of half-through and through arch bridges, the bridge health monitoring process and the concept of bridge health records are proposed. And the health indicators and characteristics of the bridge health records are analyzed. When monitoring the bridge health, the standard model and health records should be established firstly. Then, the inspection object and observation index can be determined, and the in-situ testing according to the monitoring process is carried out. Finally, comparing the measured data of each index with its reference value in the health records, the working condition of the bridge can be analyzed. Taking Liujiang Bridge on Beijing-Hong Kong-Macao expressway as an example, the implementation of health assessment is illustrated. The monitoring results show that the 4th span of the bridge was in good health at that time.
