To protect neighboring many residential buildings and public facilities, blasting in the direction of house collapses of masonry has a buffering effect on vibration reduction of Earthen berms, also laying a flexible buffer layer to reduce the collapse shocks.

　　南方日报讯 (记者/刘茜 通讯员/王建锾)一声巨响，一栋高63米的18层违章建筑瞬间爆破拆除！昨日上午，位于广州市花都区新街大道的违章建筑、花季公寓楼房被正式爆破拆除(如图，梁文祥摄)。据了解，这是目前广州拆除的最高违章建筑。

　　现场爆破技术总指挥、广东中人集团建设有限公司爆破公司总经理张北龙介绍，这是目前拆除技术难度最大的爆破建筑之一，其周边环境复杂，距离周边建筑十分近，在该违建北面13米远就有加油站，而南面距离居民楼只有6米，东面还有学校和厂房，西面则是公路，大楼地底11米深处还埋有煤气管线。为保护周边众多居民建筑和公共设施，爆破施工队在楼房倒塌方向上砌筑了具有缓冲作用的减振土堤，还铺设了柔性缓冲层，以降低塌落震动。另外，还在保护目标与楼房倒塌触地点之间开挖了减振沟，以确保爆破震动和塌落震动不对保护目标造成任何损坏。

　　笔者在现场看到，爆破拆除从第一响雷管起爆到大楼全部倒塌，持续时间6秒，成功实现爆破拆除。
