| Abstract: | Taking the large-scale railway bridge construction linear monitoring project as the research object,this paper discussed the target significance and technical method of linear control monitoring,established simulation model for calculation and analysis,used measurement monitoring technology to collect the parameters affecting the linear and stress on site,and introduced the specific monitoring method and process in detail.Through the comparative analysis of the field monitoring data and the theoretical calculation value,the elevation control in each construction stage was accurate,the elevation error was within the control range,and the stress change rule of the main beam control section was consistent with the theoretical calculation,so as to achieve the expected goal of linear control. |
