The invention provides a subway tunnel provided with programmable logic controllers (PLCs). By means of the subway tunnel, the technical problems that in existing subway tunnels, submersion-proof doors cannot be closed, and the dropping of connecting segments is not smooth are solved. The subway tunnel provided with the programmable logic controllers (PLCs) comprises a tunnel body, bus-bar structures used for supplying power to a vehicle and submersion-proof doors capable of closing the tunnel body are arranged inside the tunnel body, each bus-bar structure comprises a bus-bar left segment, a bus-bar right segment and a connecting segment which is located between the bus-bar left segment and the bus-bar right segment and used for connection, each connecting segment is detachably arranged between the corresponding bus-bar left segment and the corresponding bus-bar right segment, the submersion-proof doors are hinged to the inner wall of the tunnel body, and each connecting segment is located at the door closing track of the corresponding submersion-proof door. The subway tunnel has the advantages that time is saved, the efficiency is higher, the stability is good, and the use is safer.
