| Abstract: | A certain subway station is a two storey reinforced concrete structure. The transverse clear span and thickness of the top plate of the station are 16 3 m and 0 8 m respectively; there are no any beams and columns below the top plate that is covered with an artificial fill (1 2 m). Two heavy duty gantry cranes are arranged along the longitudinal shaft of the station at the surface above the top plate, and the foundation for one track of the cranes is laid on the fill above the top plate′s midspan. Therefore, the problem to be solved by the design of the track foundation is how to ensure that the load of the top plate due to the wheel pressure of the cranes is less than that permitted by the top plate. |
