Abstract:

The original design of Dalian Jiaotong University Station of Line 2 of Dalian Metro is changed so as to overcome the dewatering and water stopping difficulties. Analysis is made on Version A design program and Version B design program so as to clarify the causes for the design changes. The shortcoming of the separate island station with attached equipment rooms is presented in terms of structural safety, service function and economic efficiency. Advices are made on the design of Metro stations in special geological conditions.
