Abstract

Abstract: In order to study the vibration influence on Jiaozhou Bay Subsea Tunnel induced by the blasting in the ramp tunnel, blasting vibration monitoring is made in the main tunnel. The propagation rules of vibration waves in the main tunnel are analyzed on basis of the measured vibration data. The propagation rules of the vibration velocity are obtained. The analysis shows that the blasting vibration velocity in the excavated section of the main tunnel is larger than that in the unexcavated section and that the vibration velocity in the unexcavated section is stable in certain range.

Key words: Jiaozhou Bay Subsea tunnel, blasting, ramp tunnel, vibration velocity
