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.

Xiaolan channel super large bridge is a stucture type adopted in the passenger dedicated railway line for the first time, and the longest span bridge of the passenger dedicated railway line, also the longest span bridge of the high-speed railway in the world with a total length of 7686.57m.. At first, the author compiles APDL command flow program by using the unit birth-death technique, establishes simulation calculation model in the construction process. The creep characteristics of concrete are also taken into account. The whole process of beam first-to-arch later stage construction are calculated and studied. Simulation Calculation and construction control research of Xiaolan channel super large bridge shows that construction control method is reasonable, the calculation program which is used in the paper is right, and using three dimensional substantiality finite element method and “element birth and death” to simulate construction process conform to reality. The bridge is safe in the construction of beam first and arch late.
