The invention provides an arched T-beam hangar tunnel structure, aiming to enable the hangar tunnel structure to have larger span and bear larger impact load and to reduce construction cost of a hangar tunnel. The arched T-beam hangar tunnel structure comprises uprights, upright bases and longitudinal beams. Both the uprights and the upright bases are transversely arranged at intervals. The longitudinal beams are fixedly connected to the top ends of the uprights on the same side. Cross beams are fixedly arranged on the longitudinal beams on two sides through cross beam support bases. Each cross beam is composed of a top plate and a reinforcing rib which are integrated fixedly. The cross section of each cross beam is T-shaped, and the longitudinal section of each cross beam is arched.
