摘要(Abstract)：

由于城市改建,江苏盐城市原燕舞综合生产大楼需要进行爆破拆除。根据该大楼的结构特点,采取了分别在南部主楼和北部副楼各开一个爆破切口,主、副楼都向南倒塌的爆破方案。起爆后大楼主体坍塌顺利、块度均匀,达到了预期的爆破效果。
Yanwu production complex building,which was located in the city of Yancheng,Jiangsu province,was subjected to being demolished in the progressing of city upgrading.Based on the structural features of this building,two blasting cuts were prepared in the main building on the south and in the subordinate building on the north respectively,hoping that both the two sections of the complex would collapse towards the south.The paper presented the blasting scheme with the anticipated blasting effects in terms of its main body's smooth collapsing and its even fragmentation.
