“品”字形空心砖砖混楼的双向爆破

Dual Directional Blasting Demolition of An Upsidedown T-Shaped Hollow Bricked Concrete Building

介绍了一次采用大时间差多段别延期双倒向爆破拆除“高宽比”较小的空心砖砖混结构楼的工程实例 ,论述了爆破方案设计。

This paper presents a case study on blasting demolition of a hollow bricked concrete building with a small height-to-width ratio. In the blasting, a multiple-staged long delay interval initiating system is adopted. The paper describes the design of, selection of parameters and engineering aspects of the blasting.
