探讨地铁区间隧道组合竖井的设计方案，通过对组合竖井和传统单竖井方案的比较，指出组合竖井方案不仅可减少竖井工程数量、缩短建井周期、降低建井成本、提高经济效益，而且符合国家关于地下空间设计及施工的相关安全法规的规定。结合这种思路，给出一座出碴、进料主井、一座专用逃生副井和一座提供通风、供电、供水等设施的服务副井的设计方案。

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.
