| 摘 要： | 砖混结构楼房的特点是整体性差 ,在爆破拆除过程中倒塌方向难以控制 ,结构自重对爆破效果影响大。本文介绍了复杂环境条件下两相同砖混结构居民楼的爆破设计方案以及实际爆破效果。通过两楼房不同爆破效果的对比 ,分析了结构自重和楼梯间对砖混结构爆破塌散范围的影响 ,提出了在砖混结构楼房爆破拆除方案设计时如何有效利用结构的重力势能的方法

| Abstract: | The brick and concrete composite constructions are characterized by poor integrity,difficult control of collapsing direction and significant influence of structural dead weight on blasting results in blasting demolition of them In this paper,the design of blasting scheme for demolition of two residential buildings with same brick and concrete structure and actual blasting results in complicated surroundings are introduced By comparing the blasting results of two buildings,the effects of structural dead weight and staircase on the control of collapsing distance are studied At the same time,the design method how to effectively use the structural potential energy in blasting demolition of a brick and concrete construction is put forward |
