摘要
对银海大厦框架结构楼房进行了爆破拆除,结合工程情况制定了爆破方案。对1～4层墙体、楼梯和电梯井进行局部预拆除,采用重心移出的方法计算爆破高度,选择三角形爆破切口和混联爆破网路,取得了理想的爆破效果。
The Yinhai frame-structure building was demolished by directional blasting. The blasting scheme was determined according to the project situation. The walls, stairs and the elevator shaft of the first to fourth floor were partly demolished previously. The blasting height was calculated by the method of removing the centre of gravity, while the triangle blasting cut and series and parallel connection of blas- ting network were designed. The ideal blasting effect was obtained.
