Abstract:

The design scheme of the vertical shafts of Metro works is discussed. The comparison and contrast between the composite vertical shafts and the traditional single vertical shaft show that the adoption of composite vertical shafts can not only reduce the works quantity, shorten the construction period, reduce the construction cost and improve the economic efficiency, but also can meet the requirements of the national safety stipulations related to the design and construction of underground space. Thus a vertical shaft design proposal, which includes one main vertical shaft for muckingout and materialin purpose, one escapededicated auxiliary vertical shaft and one auxiliary vertical shaft for the purpose of ventilation and power and water supply, is made.
