To reach the optimum mechanics state of long span prestressed concrete cable-stayed bridge after it erected by construct control, a method is proposed to identify, predict and adjust parameter in construct control of cable-stayed bridge, which integrates the minimum square method, grey prediction theory model and influence matrix adjustment method compositively. The method is also verified by construct control of the longest span prestress concrete bridge in Asia, and the effect of construct is very successful. This work of con-struct control can absolutely demonstrate the validity and practicability of the method.
