The invention relates to a structure for inhibiting water flow cavitation of an outlet structure. The structure comprises communicating pipes buried in the outlet structure, an inlet end of each communicating pipe is externally connected with a pressurizing device, an outlet end of each communicating pipe is communicated with an overflowing wall surface of the outlet structure, and the outlet end of each communicating pipe is a shower head type porous orifice or single-pore orifice. Air or water is injected to a low-pressure area of the overflowing wall surface by the aid of the pressurizing devices, energy compensation is performed on water flow in the low-pressure area, internal pressure of the water flow is increased, flowing state of vortex water flow is improved and separated, cavitation number of the water flow is increased, formation of cavitation bubbles is inhibited, and cavitation of water flow is prevented from the source. The structure is applicable to corrosion prevention of high-velocity water flow outlet structures of hydraulic and hydro-power engineering.
