Measurement and Analysis of Environmental Vibration Caused by Blasting Excavation of Foundation Pit in Town

摘要

According to two national standard that "Standard of Vibration in Urban Area Environment" (GB 10070-1988) and "Measurement Method of Environmental Vibration of Urban Area" (GB 10071-1988),the environmental vibration testing on blasting excavation of foundation pit in town was carried out.And the change characteristics and the propagation laws of environmental vibration caused by blasting excavation of foundation pit were discussed,through processing and analyzing the testing data and calculating the level of vibration acceleration.Proposed the point that the environmental vibration should be lead into the research on blasting vibration,in order to meet higher demands of the people for environmental safety.This approach can also help to reduce blast vibration disputes,and to ensure the safety and smooth implementation of the blasting excavation of foundation pit in town.
