Analysis On The Application Of Bridge Construction Monitoring And Gray System Theory

With the development of high-speed railway lines, China have been constructing a large number of railway bridges. Because of the high speed of the railway, the bridge linear ride has a very high demand, and the importance of the bridge construction monitoring have become increasingly prominent. Therefore, this article mainly focused on the bridge construction monitoring and the application of gray system theory. The main work and achievements are shown as follows.1、Conducted a systematic analysis of the bridge construction monitoring method,and described the purpose, methods, analysis method of monitoring, and so on.2、Based on the model unit division, process definition, calculation results and other content, the construction monitoring of the modeling idea and process were introduced, which made the results more relevant.3、The sensitivities of different parameters of bridge structure on bridge construction monitoring were analyzed. What’s more, the effects of different parameters on the deflection of bridge impact degree were obtained through single variable method by the sensitivity analysis.4、According to the continuous girder bridge monitoring data of Bridge XiaoDongJiang32+48+32m, it was confirmed that construction monitoring played a good control effect on the bridge linear.5、According to the continuous girder monitoring data of bridge XiaoDongJiang32+48+32m, the gray theory model was used to predict the construction data. And the predicted results were compared with the actual measurement result. The results confirmed the practical application of grey system theory in construction monitoring.
