摘要(Abstract)：

以复杂环境下一座桁架结构拱式桥控制爆破拆除为例,介绍了爆点位置的选取、爆破参数及安全防护措施,并对爆点部位的炮孔布置、装药量和爆破网路等进行了详细描述,爆破振动和飞石被较好地控制,爆破取得了良好的效果,可为类似桥梁拆除爆破提供经验和参考。
Taking controlled blasting demolition of a truss structure arch-bridge which blasting surrounding environment was very complicated for example,the selection of detonation point position,blasting parameters and safety protection measures were introduced,meanwhile blast holes layout of detonation point region,charge weight,initiation network and so on were described in detail.Finally blasting vibration and fly rock were better controlled and good blasting effects were obtained.It could provide experience and reference for the similar projects.
