Abstract

In tunnel construction, blasting vibration has great influence on buildings and roads nearby. It is particularly important to discuss the influence scope of blasting vibration. This article focuses on the blasting vibration influence scope of the existing roads nearby through the blasting vibration velocity in-situ monitoring of key points with the case of blasting construction of Baohan highway project. The conclusions are as follows: the dominant frequency of blasting vibration is between 10-50Hz during the monitoring of the tunnel blasting construction, so that the existing roads nearby will not resonate with blasting. Based on the results of this in-situ monitoring, for the general blasting construction, the vertical vibration velocity should be principally monitored because it is higher than the radial and tangential vibration velocity and it is significantly destructive to the buildings. To ensure the safety of structures and transportation of the existing roads, the blasting vibration velocity of key points is supposed to be 2.0cm/s for existing roads of the shallow-buried tunnel underpass with large cross-section and soft surrounding rock. Furthermore, the data shows that the influence scope of blasting vibration wave to the existing roads is about 30m, which is consistent with theoretical calculation results. Therefore, these results can provide references to the general tunnel constructions.
