Applications of Grey System Theory to Construction Control of Cable-Stayed Bridge
Based on the grey system theory, and combined with the construction features of cable-stayed bridges and construction control method, the paper takes the cable-stayed bridge under construction as the interferential grey technology system with physical prototype and analyzes the random process as grey process in line with grey system theory. The grey model is established by the initialize heights of main girder and cables’ tension as two control inputs of system during the construction of the cable-stayed bridge. Through the feedback information and rectifying the grey model, the initialize heights of main girder and the cable force of next construction stage are predicted in order to control the bridge configuration and cable tension successfully.
