摘　　要：本文采用人工定期测量、自动化监测及日常巡检3种方式对超重超限车辆通行的某桥梁进行监测,监测期为48周。监测结果显示:人工定期测量各跨桥面挠度值、各墩台沉降及墩台倾斜值处于正常范围;自动化实时监测桥梁挠度、应变均未超过预警值。监测结果与桥梁实际状况相符。基于上述监测结果,说明人工巡检、人工定期测量及自动化监测3种方式相结合对监控超重超限车辆通过桥梁是有效的。This article uses three ways of artificial periodic measurement,automatic monitoring and daily inspec- tion to monitor a bridge passing over the overweight and ultra limited vehicles for 48 weeks.The monitoring re- sults show that the deflection values of each cross bridge surface,the settlement of each pier and the tilt of the pier and abutment are in the normal range,and the deflection and strain of the bridge are not more than the ear- ly-warning value in real-time monitoring.The monitoring results are in accordance with the actual situation of the bridge.Based on the above monitoring results,it is proved that the combination of three ways of manual inspec- tion,artificial periodic measurement and automatic monitoring is effective to monitor the overweight and ultra limited vehicles through the bridge.
