The utility model discloses an anti-vibration structure for preventing resonance of an underground pump station and a high-rotating-speed unit, anti-vibration grooves are formed in rock walls on the outer sides of an upstream side wall and a downstream side wall of an underground pump station plant, the anti-vibration grooves extend to the floor elevation of a motor layer from the top of a water inlet pipe/water outlet pipe, and system anchor rods are arranged in the anti-vibration grooves. One end of the system anchor rod is anchored into the rock mass, the other end of the system anchor rod is connected with the side wall reinforcing steel bar through bending of the end of the anchor rod, and concrete is poured in the anti-vibration groove. The concrete in the anti-vibration groove and the concrete of the side wall of the underground pump station factory building are poured at the same time to be integrally formed. The integrality of the surrounding rock and the plant structure can be effectively improved,
