复杂条件下的单层地铁车站深基坑工程制约性因素较多，因线路设置的特殊性导致类似工程较少，结合无锡地铁2号线友谊路站对此类基坑工程设计进行了探讨，对两种常用的工法-半盖挖顺作法和半逆作法进行了技术经济比较，半逆作法对环境影响较小，但半盖挖顺作法技术成熟、工期短且可实施性强，总造价相对节省约597万元。无锡地铁2号线友谊路站采用了半盖挖顺作法施工，工程实施效果良好，可为后续工程提供参考。

There exist many restricted factors in the engineering design of deep foundation pit for the monolayer metro sta-tion in complication condition,and the speciality of subway line set leads to the few cases of similar engineering design. The engineering design of this type of deep foundation pit is explored here with Youyi Road Station of Wuxi Subway Line 2.Through comparing the economical efficiency and technicality of semi reversed construction method and semi ordinal-covered excavation method,it is found that the first method has less effect on the environment.However,the semi ordi-nal-covered excavation method is more mature in technology,shorter in duration,stronger in implementation,and less 5 .97 million yuan in construction cost than the semi reversed construction method.The semi ordinal-coverd method is used in Youyi Road Station of Wuxi Subway Line 2,and its implementation effect is very good.This method could be re-ferred to the further constructions.
