Experimental Study on the Effect of Vibration of Pile Foundation Construction

Abstract

Impact drill holes into the pile construction technology is widely used in pile foundation construction job, construction vibrating pile thus to bring the impact of the increasingly prominent on the surrounding environment, the impact of this article on the construction site of a pile of drilled hole pile construction vibration effects on the surrounding environment experiment monitored by the monitoring data analysis found that the peak acceleration increases with distance attenuation occurs quickly, on the basis of analysis of pile foundation construction vibration velocity, frequency, and duration of the impact on the surrounding buildings, it is found that the frequency of vibration velocity with less impact on the housing, the duration of the construction will have an impact. Finally, analysis of the impact acceleration caused by the building structure from the perspective of seismic intensity, vibration intensity was found equivalent vi degree seismic intensity of little effect on the surrounding structures. Furthermore, the greatest impact of vibration on the residential buildings, by the way of excavating vibration attenuation ditch to control effect of vibration is proposed.
