| Abstract: | This paper describes the process of the construction control of Beiguan Bridge,a self-anchored suspension bridge.Mechanical properties of this type of bridges in construction were studied.An effective tensioning method was introduced,and completed system transformation by three times of tensioning.The configurations of the main cables and of the stiffening girder,position of the saddles and force of the hangers were properly controlled. |
| Keywords: | Self-anchored suspension bridge Construction control Weak interference Alternately tensioning method |
