Abstract: Based on Qingdao metro Line 3 project that was built in shallow buried hard granite stratum, the monitoring data of horizontal channel blasting vibration in test sections are analyzed by using field measurement and statistical regression method. The relationship among the maximum surface vibration velocity, the maximum single shot charge and main frequency distribution under drilling and blasting construction conditions is systematically studied, the empirical formula of vibration attenuation suitable for this stratum is summarized，and the maximum single charge of blasting construction in this section is predicted based on the site measured data fitting. It is concluded that in the process of tunnel blasting, the vertical vibration velocity is the largest, and the vibration velocity decays exponentially with the increase of propagation distance. Due to the strong "clamping" effect of the surrounding rock, the blasting vibration of the cutting hole is the largest, and the energy distribution of the blasting vibration wave can be well controlled by the staged initiation. The main frequency of blasting vibration is mostly distributed in the range of 20~70 Hz, that has no obvious correlation with the distance between blasting center and the charge weight. In order to avoid the resonance with surrounding buildings, the simultaneous initiation of multiple detonators should not be adopted, and the maximum single shot charge quantity should be strictly controlled.
