| Abstract: | The stone arch bridge to be demolished was located in residential area of the city in very complicated environment. The first considering factor was blasting safety, and for this reason, stage delay blasting method was employed in the construction, achieving the blasting effect that the bridge collapsed entad along higher reaches of the river. The paper introduced blasting program, blasting parameters and safety precautions, which can be referenced by similar engineering. |
