The invention discloses an effective coupling method for a high-strength concrete surface detector. A first drilling hole is arranged on a wall surface. A second drilling hole is arranged in the first drilling hole. An expansion screw is arranged in the second drilling hole to fix a detector disposed in the first drilling hole and a gap is filled to reduce a whiplash effect caused by the exposure of the detector. The method can ensure the effective coupling between the main body of the detector and a target body, can achieve the acquisition of high signal-to-noise-ratio and high-resolution vibration signals, can reduce the construction intensity and can minimize the damage of construction to the target body.
