Application of stonework blasting technology in the transformation of existing railway lines and the construction of double-tracking railways

摘要

Aimed at the safety-controlled blasting technology widely applied to the transformation of existing railway lines and the construction of double-tracking railways, this paper analyzes the effects of the blasting parameters on overbreak and vibration of blasting, puts forward a few control measures which may help minimize the destructive effects of explosion and blasting vibration so as to maintain the slope stability and improve blasting safety, also suggests one method for the calcualtion of the stability of slopes to be affected by blasting.
