Construction monitoring of cable stayed bridge with unequal span and single tower and single cable plane

In order to improve the efficiency of bridge construction, a bridge construction monitoring method based on MIDAS civil finite element software is designed in this paper. Taking the construction monitoring of the main bridge of Huangshuihe bridge on Tonghai road in Xining City as an example, the monitoring parameters of the top deflection of the main tower and the simulation of temperature change during construction are described in detail. The effectiveness of the method is verified by the comparative analysis of theoretical data and measured data.
