七层框架爆破拆除工程实践

Practice of a Seven-floor Frame Blasting Demolition

介绍了利用定向爆破方法拆除钢筋混凝土大楼的方案选择、参数计算、施工方法和安全措施。通过试爆,取得了较为准确的孔网参数,爆破后楼房梁柱全部解体,周围建筑物完好无损。

The paper introduces key factors such as plan selection, parameter calculation, construction method and safety precautions during the demolition of reinforced concrete building by directional blasting. A more accurate net parameter is acquired through the blasting test, the building beams are all destroyed but the ambient buildings are all in good condition after blasting.
