Abstract:
The large transfer station has characteristics such as multiple architectural functions, high usage standard and complex structural types due to large rivercrossing shield tunnel. The issues, i.e. the transfer mode, building scheme, usage function, space efficiency, project risk and structural stress, are discussed by taking operation Xujiapeng Station on Wuhan Metro Line No. 8 with distinctive architectural space; and some feasible and rational engineering design innovation measures are put forward. With the help of lifting space, enlarging column span, permeable atrium, special decoration and different levels of spatial layout, a high and large spatial effect of the station is realized. The safety of the superdeep large foundation pit under high confined aquifer conditions of the firstclass terrace of the Yangtze River is guaranteed by rational support system and water stopping scheme. The problems such as large span of station and design and opening of large atrium structure are solved by upliftresistant piles on the floor, platewall joints with axillary, temporary force transfer system and beamcolumn transfer system. The station public space is saved by innovative Ytype escalator column and suspension overpass.
Key words: Wuhan Metro, Xujiapeng Station, transfer station, distinctive architectural space, architectural function, structure type, design measure
