摘要(Abstract)：

长春市伪满皇宫博物院门前的4栋七层楼房采用了定向和逐段解体的爆破方法同时拆除,降低了楼体坍塌时对地面的冲击强度。此方案在爆破拆除过程中,不但考虑了每栋楼之间是相互影响的,而且也是可以相互利用的,因此采用了交叉延时爆破,使每栋楼房在倒塌落地前可以互相阻挡爆破飞散物。此外,爆前预拆除全部由机械来完成,加快了施工进度。这些技术措施确保了多栋楼房同时爆破拆除圆满成功。
Four 7-storey buildings which located in front of the Imperial Palace Museum of"Manchu State"in Changchun,Jilin Province,were demolished by using methods of directional blasting plus segment collapsing for the consideration of lowering the impact on the ground.And moreover,considering the fact that each building got not only blasting involved,but also could be cooperated,the blasting employed intercrossing delay operation which made each building be one blockage for the flyrock resulted from the previous collapse.Besides,the job of pre-remove was all finished by mechanized production,speeding up the construction.The blasting ensured a full success owing to the use of the all above reasonable technical measures in the demolition.
