CONSTRUCTION TECHNOLOGY OF THE PRESTRESSED CABLE FOR REFORMING THE AWNING PROJECT OF LIAOCHENG RAILWAY STATION

The Liaocheng Railway Station was rebuilt in May, 2010.Beam string was used for the new platform． Semi-span installation was used for beam string, and high roller-oriented traction installation method used for the prestressing cables.The installation method solved the limitations of the cable installation space and ensure the safe distance during construction.It was introduced in detail the construction technology of prestressed cable.Through a comparison between the simulated data and measured results, applying of the prestress could meet the requirements of the design and satisfy the provisions of the relevant norms and standards.The construction technology and characteristics of this structure were proposed, which provided experience for reforming railway station auning with similar structure．
