摘要(Abstract)：

待拆的石拱桥位于城市居民区,环境复杂,爆破安全是首要考虑的因素。采用分段延时起爆法,达到桥体向内和向上游倾倒的爆破效果。本文所阐述的爆破方案、爆破参数、安全防护措施以及施工中应注意的事项,可供类似工程参考。
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.
