Research On Construction Control Technology Of Eleven Spans Continuous Beam In Jiangdong Bridge

Bridge construction monitor and control is an important part of the bridge construction technology. It is very important of effective construction monitor to the safety in construction and its progress, and It is also necessary to ensure internal force,stability and configuration of the bridge meet the requirements of design.Hangzhou Jiangdong Bridge lies in the northeast corner of this city. Based on the construction of eleven spans continuous beam bridge which is not for navigation, the research on the long span and long unit continuous beam bridge construction control technology and the implementation have been taken. In this paper, the domestic and foreign present research situation and the main control methods have been summarized firstly, and then choose the most suitable method for the bridge. Because the span and the unit are all long, and the construction is very complex, we established the FEM by GQJS according the construction process and analyzed it. The measured data, expected data and theoretical data have been compared based on the elevation and stress monitor data from the key crosses which provides the basis for the parameter adjustment. At last, the article has carried on the supplement development and consummation regarding the GQJS software's monitoring module, and has optimized the data processing and contrast feedback process, and then use it during the construction control.At present, the right part of the bridge has been closed up and the configuration has an ideal result as well as the stress.
