盖挖顺作法、盖挖逆作法和盖挖半逆作法这3种工法的选型决策不仅需要考虑工法的可行性，还需要考虑工期、经济性以及社会效益等因素。为了得到3种工法选型决策的评价体系，以青岛五四广场地铁车站为例，运用层次分析法对该地铁车站进行3种工法的选型研究，得到盖挖半逆作法为该地铁车站的最优工法，结果符合实际工程经验；通过对有限元计算结果和现场施工监测结果进行分析，得到盖挖半逆作法表现良好，为最优推荐工法。

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.
