| Abstract: | Wuhan Station has ten parallel arc rigid bridges. Because of tight construction period,complex situations,and considering period,cost and technology condition comprehensively,steel truss support system is chosen. The structural setting for support system is introduced,as well as some structural methods are indicated by checking,such as bailey beam joint should be of alignment with support,and distributive girder is connected with bailey beam by clamping piece type bolts. Furthermore,the integral installatio... |
