摘　　要：用控制爆破方法拆除了一座长282m、宽9.5m的双曲拱桥。根据双曲拱桥的特点,在拆除爆破过程中所采取的炮孔布置及装药量、起爆网路设计、爆破安全防护措施等技术,可供类似工程参考。The paper discussed a method of controlled blasting employed in demolition of a double arch bridge with a length and width of 282m and 9.5m respectively. The employed borehole layout,detonating network design and measurements of security protection in the blasting demolition were all based on the characteristics of double arch bridge which were of reference value to the demolition of old bridge in future.
