【摘要】 结合江苏田湾核电站减震沟开挖的工程爆破震动监测实际,提出了合理的结构物振动监测方法,分析了在爆破地震波作用下核岛结构物的振动加速度、振动速度、振动持续时间以及速度频谱的特征,完善了核岛结构物对爆破震动的安全控制要求。更多还原

【Abstract】 Taking the monitoring of blasting vibration in digging blasting of damping ditch of Tianwan nuclear power station in Jiangsu as back-ground. A reasonable measure of structure vibration monitoring is given. The authors analyze the characters of vibration acceleration, velocity, continuance and velocity frequency spectra of nuclear reactor structure by blasting vibration in the article. The conclusion helps to consummate the safety controlling criterion of the nuclear reactor construction.更多还原
