复杂结构热电厂厂房爆破拆除

摘要

The explosive demolition of turbines and boilers' workshop in Maoming thermal power plant was intro duced. These workshops' structure was complex and there existed a lot of concrete beams and floors linking in many places,highly stable as a unity. Demolition scheme including preprocessing,options of cut height,blast parameters' calculation of column,charge's setting,firing network designing and blast safety protection. The results indicated that workshops are demolished successful and ensure the security of adjacent buildings.%介绍了位于茂名热电厂内汽轮机及锅炉厂房的爆破拆除.该厂房结构复杂,厂房之间存在多处混凝土横梁及楼板链接,整体稳定性强.爆破方案包括了预处理、切口高度的选择、立柱爆破参数的计算、药包设置、起爆网路设计和爆破安全防护.结果表明:厂房顺利倒塌,确保了周围建筑物的安全,爆破达到了非常理想的效果.
