Ⅱ.General
The superstructure of Madura approach bridge is the continuous beam with the layout (40+7×80+40)m. The width of single part is . The single part is single-box &single-cell box girder. Cantilever concreting of segments #-~8# is done by form traveler.
Length of segment of box girder: the respective length of the segment No. 2#~3# is 4m. The respective length of the segment No. 4#~8# is .
The weight of major segments of box girder: the weight of segment # is
and the weight of segment # is .
The width of the top surface of the box girder is . The width of the bottom plate is .
The height of the box girder at the root is . The height (cross section) of the box girder at middle span and the closure segment is .
The thickness of the bottom plate of the box girder from the root to the end of the cantilever concreting section varies and descends from to 26cm.
The thickness of web plate of the box girder. The thickness of the web plate of the box girder segment No. 2#~3# is 60cm. The thickness of the web plate of the box girder segment No. 4# varies within 60cm~45cm. The thickness of the web plate of the box girder segment No. 5#~8# is 45cm.
The thickness of the top plate of box girder segment No. 2#~8# is 26cm.
