Abstract Research purposes: The line 7 of Wuhan metro is an important line to connect the new west downtown with the new south downtown in long － range plan． The 18 stations ，including 9 transfer stations will be built in the first phase project of the Line 7． The Xujiapeng Transfer Station is the first station close to the Yangtze River in the south，it is located in the cross between the Heping Avenue and Tuanjie Road and it will transfer with the Line 5 and the Line 8 of Wuhan metro． So this station will be a three － line transfer station． The researchs on how to deal with the transfer relation among the three lines，how to do the pre － remaining works in the joint plan for the transfer station and how to deal with the relation with the public works are the key and difficult points．
Research conclusions:According to the planned alignments of these three lines and the environment conditions around the Xujiapeng Transfer Station，it is proposed the " 工" shaped transfer mode should be adopted for the Xujiapeng Station． The river － crossing tunnel should be designed and constructed with the station at the same time to reduce the unnecessary repeated construction． The research presented in this paper can provide the reference to the similar works．
