The invention discloses a thin-wall titanium alloy hollow support plate with a discontinuous reinforced structure and a processing method thereof, the thin-wall titanium alloy hollow support plate with the discontinuous reinforced structure is a titanium alloy closed thin-wall component part used for connecting a shunting inner ring and a shunting outer ring on a turbofan aero-engine, and the structure adopts superplastic forming diffusion connection. The superplastic forming diffusion bonding is pressurized in a high-temperature vacuum state to form solid-phase permanent bonding, and then the wall surface of the hollow support plate is pressed by high-pressure inert gas to generate plastic deformation so as to obtain a molded surface profile required by the hollow support plate. The machining method is simple, reliable and convenient to operate, the machining problem of the discontinuous reinforced structure hollow supporting plate is effectively solved, and the problems that welding deformation existing in
