摘要为了分析爆破振动对精密仪器的影响，以Intel集团场平爆破振动为案例，结合Intel公司提供的加速度功率谱密度要求标准和大连地区的爆破振动规律，设计了试验方案。对现场监测数据分析发现，原定控制点位置，无论深、浅孔爆破，在设计起爆网络下，振动速度均不大于0.02cm/s，且加速度谱密度值均小于给定标准。这种加速度谱密度的控制方法不仅能降低爆破施工的经济成本，同时也为复杂作业环境下爆破振动的安全评价提供可靠依据。

Abstract：In order to analyze the influence of blasting vibration on precision instrument, taking the land leveling blasting vibration of Intel company as a case, combining the standard of blasting vibration acceleration spectral density provided by Intel company and the law of blasting vibration in Dalian, the test scheme was designed. The monitored data analysis showed that under the designed detonation network, the blasting is either deep hole style or shallow one, the vibration velocity at the original control point position is no more than 0.02 cm/s, and the vibration acceleration spectral density values are less than the given standard; this control method can not only reduce the cost of blasting operations, but also provide a reliable basis for the safety assessment of blasting vibration under complex operating environment.
