Claim:
A guideway structure for a high-speed track-bound transportation, comprising: a longitudinally-extending lower-layer main load-bearing girder; an upper-layer track surface structure, comprising: a plurality of main body reinforced concrete plate girders arranged end-to-end in a longitudinal direction, and being disposed over said main load-bearing girder, a gap being provided between each adjacent plate girder to allow for expansion and contraction; a plurality of longitudinally-extending steel elements defining gliding surfaces upon which a magnetic levitation train glides, and being respectively disposed on opposite lateral sides of said plate girders; and a plurality of connecting elements integrally attaching respective plate girders to respective steel elements; and a connection-mechanism that comprises supporting steel girders, weld nails, high strength bolts and steel bearing plates, said supporting steel girders being connected with the lower-layer main load-bearing girder by the high-strength bolts, and the steel bearing plates, the weld nails on a top of said supporting steel girders being deeply inserted into respective post-pouring holes on said reinforced concrete plate girders, wherein each of the reinforced concrete plate girders is supported by at least three of said supporting steel girders, including a rigid supporting steel girder disposed at a longitudinal intermediate portion of each respective reinforced concrete plate girder, and flexible supporting steel girders disposed respectively at each end of the respective reinforced concrete plate girder, wherein the rigid supporting steel girder has a plurality of longitudinal stiffening plates disposed thereon to increase its rigidity relative to said flexible supporting girders, wherein the flexible supporting steel girders are spaced apart from said rigid supporting steel girder, wherein said supporting steel girders raise said upper-layer track surface structure over said lower-layer main load-bearing girder so that there is a space therebetween, and wherein the lower-layer main load-bearing girder is connected to the upper-layer track-surface structure using the rigid supporting steel girders and the flexible supporting steel girders.
