鞍钢专家接待楼地表以下土石方爆破振动研究

Blast Vibration Research of Earth and Rock underneath Angang Hotel

介绍采用深孔综合控爆技术（底部间隔装药、孔内微差、逐孔顺序起爆、开切预裂缝等）使邻近爆区的建（构）筑物所产生的振动强度减弱到最低程度，确保鞍钢专家接待楼地表以下土石方爆破过程中邻近建（构）筑物的安全，文中着重论述通过试验研究确定底部间隔装药和开切预裂缝后的综合减震效应（减震率）；阐明所进行的爆破地震强度监测及其结果分析，在整个爆破过程中为确保邻近建（构）筑物安全所起的指导作用。

To ensure the safety of the buildings around the Angang Hotelduring the blasting of the earth and rock underneath it,the multiple control blasting technology with large diameter and long hole is introduced. The damping effect of the space charging at the bottom and spliting cracks in advance are discussed.
