Abstract:

Not only feasibility, but also construction schedule, economic efficiency and social significance should be considered when bottomup cutandcover method, topdown cutandcover method or semitopdown cutandcover method is selected. In the paper, the selection of the proper construction method for Wusiguangchang station of Qingdao Metro is studied by means of AHP method. The study shows that the semitopdown cutandcover method is the best construction method for the Metro station. The study result agrees with the engineering experience. Analysis is made on the FEM calculation result and the monitoring result, which shows that the semitopdown cutandcover method has good performance and should be the proposed construction method.

Key words: Metro station, semitopdown cutandcover method, AHP method, questionnaire survey
