Effect of excavation blasting vibration on adjacent buried gas pipeline in a metro tunnel

Abstract. Through the analysis and research on the vibration effect caused by the urban New Austrian (shallow embedded) metro tunnel blasting construction, the main harming effect of the blasting vibration on the surface buildings is summarized. According to the actual condition on the site of blasting construction in No.2 line of Dalian metro tunnel, the reasonable vibration monitoring plan for blasting vibration wave is established. At the same time, by means of the regression analysis about the monitoring results of blasting vibration, the vibration wave’s regression formula are set up, which can expression the correlation among the vibration velocity, the charge weight, the distance between the blasting fountains and the buildings. The results show that the Sadaovsk formula can be use to describe the effect of the metro tunnel blasting construction on the surface buildings accurately and reasonably in this construction segment. This kind of regression analysis method can be use to direct subsequent blasting excavation.

Buried Gas Pipeline

Results of a field study in which vibrations due to pile driving were monitored are presented. The objective of this study was to determine the effects of pile driving on a buried gas pipeline. It was concluded that, at this site, the vibrations produced through pile driving were not significant enough to cause damage to the pipeline at distances greater than 1.2 m from the pile. Key words: pile driving, vibrations, granular soils, fill, field study.
