The invention discloses a laminated station entry and exit structure of an underground railway station. The laminated station entry and exit structure of the underground railway station comprises a tunnel and a tunnel support structure used for anchoring a tunnel vault and tunnel side walls. The tunnel has at least two layers of passages, and at least one layer of passages is used as an exit passage for connecting an exit layer of the underground railway station with a ground layer of the ground station building; and at least one layer of passages is used as an entry passage for connecting anentry layer of the underground railway station with an underground layer of the ground station building. In the design of the laminated station entry and exit structure, the tunnel is divided into upper and lower independent passages, so that passenger flow in and out of the station does not cross, the efficiency of passengers entering and exiting the station is greatly improved, potential safetyhazards are reduced, and congestion is avoided; and at the same time, the design of the laminated station entry and exit structure can reduce the number of caverns and the project investment.
