Abstract To explore the influence of blasting vibration on underground pipelines, the peak particle velocity used as criterion of blasting vibration and the strain used as criterion of underground pipeline affected by vibration. Using TC-4850N blasting vibration measurer and DH3820 static strain test system to monitor in the blasting construction of a project. They were measured surface vibration signal and the axial and circumferential strain of the pipe. Fitting analysis of peak particle velocity and pipeline strain showed that exponential relationship between blasting vibration peak particle velocity and axial and circumferential strain of corresponding underground pipelines. The fitting relationship combined with the attenuation law of blasting vibration to predict that the maximum ground peak velocity which the pipeline can support, which was 20.37cm/s, the safe distance was 25.25m. Thus it needs to be improved that prohibit blasting in the range of 50m and forecast the safe distance of underground pipeline according to the actual situation.
