摘要(Abstract):

介绍了复杂环境下15层L形框架结构商务楼定向爆破拆除实例,结合工程难点,制定了爆破方案,并阐述了爆破拆除的设计思路,以及爆破切口的选择、爆破参数的选取、预处理、起爆网路设计及安全防护等控制楼房准确倒向的技术措施,并对爆破灾害采取了有效控制措施,达到了预期效果。
The directional blasting demolition example of a 15-storey business building of L-shape structure under complicated environment was introduced.According to the difficulties of engineering,the blasting scheme was formulated and the blasting demolition design thought was stated.The technical measures were also elaborated in order to control the exact backward of the building,such as the selection of blasting cuts and parameters,pre-processing,design of detonating network,and the safety protection.The anticipated effect was reached by the effective control measures for blasting disasters.
