2栋混合结构楼房纵向延时定向倾倒爆破拆除

介绍了2栋砖混结构楼房采用纵向延时定向倾倒爆破拆除。通过采用纵向逐段延时与定向倾倒相结合的爆破设计方案,达到了楼房在爆破倾倒过程中结构充分解体、减小爆破单响药量、降低结构触地振动的目的,同时对采用纵向延时方式与传统的整体定向倾倒方式的爆破振动和塌落振动进行了分析。爆破效果与设计方案吻合,达到预期爆破效果。

Demolition of Two Brick-concrete Buildings by Longitudinal Delay and Directional Blasting

The longitudinal delay and directional explosive demolition of two brick-concrete buildings were introduced.The application of longitudinal delay and directional collapse blasting technique made structure collapse during the process of blasting demolition.The technique could effectively reduce the charge amount per delay and reduce the collapse vibration.Meanwhile,the blasting vibration and the collapse vibration were analyzed compared with the traditional collapse way.The blasting results were agreed with ...
