Building Safety Control Technology Of Blasting Vibration

Blasting vibration is much compromise to construction, so it has been extensivgjattention by scholars for long time. Using the combined method of theory analysis and the spot examination, Discussing blasting vibration to the city construction, analyzing the mass locale data and influence characteristic of blasting vibration to the difference city construction, combining criterion for damage induced by blasting vibration, This article bring forward security control measure to reduction the blasting vibration to the city construction.It also studied on dynamic response of multiplayer construction to blasting quack host frequency, indicated the height of multiplayer construction had magnify action to demolish vibration rate. The main frequency of demolish vibration rate had much affection to this magnify action, if the main frequency is much low, the magnify action will be much higher. If the main frequency is near or equal to self vibration of multiplayer construction, the resonate may be occurred, then multiplayer construction will be severity destroyed.
