基于健康监测系统下乌兰木伦桥状况分析学位论文.doc

摘要 通过对鄂尔多斯的乌兰木伦大桥桥梁进行健康监测，得到风荷载监测、空气温湿度监测、结构温度监测、主梁振动监测、应力应变监测、斜拉索索力监测数据。通过监测测到的数据以及图像分析研究，主要取得如下结论： 通过数据分析，（2） （3）桥梁动力结构响应监测：主梁振动监测、应力应变监测、斜拉桥索力监测数据在设计值范围内，未发现异常； （）。 Abstract Through to the ordos ulam wooden bridge bridge health monitoring, and get the wind load, air temperature and humidity, the structure temperature monitoring, girder vibration monitoring, stress and strain monitoring, suspension cable force monitoring data. Through the analysis of the data and image monitoring and measurement to study, mainly has the following conclusion: (1) through the year data of structural health monitoring system and image analysis, the whole zautra a wooden bridge structural health monitoring system working properly, the hardware and software, monitoring data is correct; (2) in the system load monitoring: wind load, air temperature and humidity, the structure temperature monitoring values are within the scope of the design of the bridge, the bridge safety of usability and components without harm; (3) dynamic structure responses of bridge monitoring: main girder vibration monitoring, stress and strain monitoring, cable force of cable-stayed bridge monitoring data within the scope of the design value, no abnormalities are found; (4) the bridge must be an organic combination of advanced manual inspection and health monitoring system, in order to effectively eliminate the deficiencies of the existing test methods; (5) at the beginning of the bridge in use, less maintenance work, focus on combining observation and monitoring system of information, establish a precise and reliable structure model, prepare the way for long-term inspection maintenance plans; (6) to advise the maintenance of the sensor health monitoring system on the outside of the structure.
