Monitoring and Analysis of Historic Building Vibration Influenced by Blasting in Complex Urban Environment

This article is based on TengChong County municipal sewage treatment plant supporting pipe network project, monitored and analyze the vibration influence on the historic building taiji bridage by the Pipe-jacking blasting construction. Via regression analysis of velocity in vertical direction of measuring points on the basis of monitoring data, obtained the attenuation laws toward taij bridage direction. The vibration signals were decomposed into IMF components by using HilbertHuang transform (HHT),analyzed the several IMF components could be acquired the timefrequency characteristics of the vibration signals. These will provide references to the similar projects.
