Abstract

In this paper the measured blast vibration signal of tunnel between Huaxin station and Huangmugang station of Shenzhen subway line 7 was analyzed, with blasting excavation way of benching tunneling construction method using different maximum charge of explosives. The peak vibration velocity and main frequency after explosion using different single section dose was comparative analyzed. The results demonstrate that: section dose increasing from 2.4kg to 3.6kg makes blasting vibration velocity bigger and main frequency lower. Meanwhile, the change of energy distribution curve at different frequency after blasting with two section dose based on HHT analyze methods was comparative analyzed. The research indicates that: the input energy through blasting vibration at low frequency (0-20Hz) becomes significantly larger, however the input energy ratio at middle and high frequency sharply decreased as section dose increased. In real construction, improving cyclical footage by increasing section dose should be used careful. A new way to control blasting vibration was proposed through the research.
