| Abstract: | Beijing Lize Rd. pedestrian bridge is of new structure and designed by stayed-cable type. The difficulties and key points of the stayed-cable pedestrian bridge are introduced. There are construction techniques from three aspects in this paper, camber before and after main beam installation, verticality of tower pier and the dragline tensioning times & force values. Through the project test, the construction by stayed-cable type is of excellence and application, which provides reference values for similar projects. |
