摘要:
为了解决环境复杂、倾倒场地狭窄条件下L型楼房的定向爆破技术和安全问题，将楼房分割为3个横截面均为矩形的独立单元，采用了中部单元向外倾倒、两侧单元定向对叠向内倾倒的爆破方案。利用定向切口承重柱的装药量择向分配的偏炸技术和延时起爆技术，在相应的复合防护体系和减振措施（隔振沟）配合下，成功实施了L型楼房的定向倾倒，确保了爆破周围建筑物和设施的安全。该设计方法和参数可为同类工程提供参考。
Abstract:
In dealing with the directional blasting technique and safety problems of an L-shaped building at a confined location with complex surroundings, a blasting design was proposed that the building would be divided into three unitssuch that the middle part would be collapsing in the lateral direction while the two sides of the building would collapse toward each other and pile upon the middle. The safety of surrounding buildings and infrastructures has been guaranteed by inclined blasting with charged explosives towards the safe side of the pillars and by ignition delaying techniques that reduce the magnitude of the instantaneous explosion, furthermore with the co-corporation of the corresponding near and remote protected package and measures of decreased earth-quakes energy. The results could be referenced by similar blast engineering projects.
