Abstract: Based on the theory of construction control, a kind of control system of large-span P.C.cable-stayed bridge is presented, which has been adopted in the construction of large-span P. C. cable-stayed bridge and has been proved applicable and effective.The bridge configuration control and cable forces control can be effectively achieved, which are valuable references for the construction control of P.C.cable-stayed bridge.

Key words: P.C.cable-stayed bridge, construction control, test of stress and cable forces, temperature amendments
