大桥安全监控技术的研究

Study of the Technology of Safety Surveying and Controlling of large Bridge

针对特大型桥梁运行期间的安全监测对精度和实时自动化的要求,探讨了在大桥的位移监测中自动全站仪精密测控的问题,对大气折光的高程测量影响和灰关联模型在大气折光系数处理中的应用进行了研究,并介绍了大桥安全监控系统的结构和安全监控中数据处理的数学模型等问题。通过结合当前大桥监控中的具体问题进行研究,取得了一定成果,有一定的应用价值。

To meet the requirement of the precision and run-time automation of the safety monitory during the large bridge’s running, the paper studys about the precise survey-controlling using the total station instrument in monitoring of the bridge, and make the research of the influence of the atmosphere refraction on elevation surveying and the application of the gray model in dealing with the refraction coefficients, and introduces the structure of bridge’s safety monitoring system and the model of safety monitoring data processing. The paper make researches of the present practical problem of bridge monitoring, has got some results, and will have some application values.
