摘要:

为研究开挖断面为6 m范围内同段位两炮孔间距对最大爆破振动速度的影响,以青岛地铁2号线延安路站侧穿166号楼为研究对象,采用数值模拟与现场试验相结合的方法,对同段起爆炮孔间距这一参数进行计算分析。结果表明: 1)在开挖断面宽度为6 m范围内,同段起爆的两炮孔间距对最大爆破振速影响不明显; 2)相邻两炮孔同段起爆比间隔炮孔同段起爆产生的振速衰减得快,即相邻两炮孔同段起爆对建筑物的累积损害量相对较小。

Abstract:

The influence of spacing of blasting holes with same detonation delay on the maximum blasting vibration velocity is calculated and analyzed by numerical simulation and field test, taking Yananlu Station on Line 2 of Qingdao Metro side crossing building No. 166 for example. The results show that: 1) The influence of spacing of blasting holes with same detonation delay on the maximum blasting vibration velocity is not obvious when the width of excavation crosssection within 6 m. 2) The reduction of blasting vibration velocity induced by detonation of adjacent blasting holes is faster than that induced by detonation of spaced blasting holes, i.e. the accumulated damage of building induced by detonation of adjacent blasting holes is smaller than that induced by detonation of spaced blasting holes.

Key words: Qingdao Metro, tunnel blasting, blasting with same detonation delay, blasting vibration velocity, numerical simulation, blasting hole spacing
