摘要(Abstract):

在减震沟开挖前后 ,于田湾核电站 2 # 核岛结构物附近进行了深孔爆破试验 ,同时进行了爆破震动监测。根据震动加速度监测结果 ,采用单自由度体系结构动力响应分析方法 ,建立了田湾核电站2 # 核岛结构物的爆破震动加速度反应谱 ,并作出了抗爆破地震设计反应谱。
Before and after excavating the vibration-reduction trench,deep-hole blasting experiments and blasting vibration monitoring were carried out in the place near to the Nuclear Power Station No2 in Tianwan.On the basis of the monitored acceleration of blasting vibration, an method for analysis of structural dynamic response of mono-freedom system was used to establish the acceleration response spectra of blasting vibration for the Nuclear Power Station No 2 in Tianwan, and the response spectra for design of vibration-resistant blasting was worked out.
