In order to improve the correctness of vibration intensity prediction in a tunnel’s field near blasting, a calculation model for the vibration velocity of the field was established based on the assumption of the linear superposition theory. Based on the measured vibration data in Beijing’s Xing-yan highway tunnel within the mileage range of YK28 + 190 to YK28 + 354, the feasibility of the calculation model was verified, the vibration law of the tunnel’s field near blasting was studied. The results showed that (1) the blasting vibration prediction model based on the waveform superposition is suitable for the near field vibration prediction; (2) in the direction of the tunnel cross-section parallel to the tunnel face, with increase in a single-hole charge, the energy density of each tunnel cross-section increases, the intensity of vibration velocity contours increases; the vibration velocity growing rate of the central measuring line is larger than those of both sides, this phenomenon is specially obvious in blasting near area; on the measuring line perpendicular to the tunnel face, the vibration velocity attenuation speed decreases gradually with increase in the distance from blasting source; (3)with increase in the number of cutholes, the vibration velocity contours shift outwards and become flat gradually; in the direction of the tunnel cross-section parallel to the tunnel face, the vibration velocity growing rate decreases gradually.
