To realize above-mentioned second purpose, the technical solution that the present invention takes is：A kind of major diameter one-tunnel two-tracks subway tunnel
Construction method, it includes following construction procedure：
1) large-diameter shield construction, is completed, forms tunnel body construction；
2) bottom plate and mid-board, are poured, wherein, bottom plate is connected with the embedded iron on tunnel body；
3) road bed board, the reserved evacuation platform connection embedded iron in centre, are poured；
4) the track laying work of subway train in tunnel, is completed；And middle part evacuation platform construction is completed, and on road bed board
Embedded iron connects；
5) laying installation of the various circuit pipelines of tunnel internal, is completed, subway train contact net is installed, forms final tunnel
Road.
Compared with prior art, the present invention has the advantages that：The major diameter one-tunnel two-tracks subway tunnel of the present invention
Uplink and downlink train is arranged in same tunnel, can reduce and take the underground space of about half, and it is easy for construction, save into
This.
