【摘要】 根据汾河水库水下岩塞爆破监测的加速度时程曲线,选用卷积分法和快速傅立叶变换法两种反应谱的计算方法得到爆破振动加速度反应谱曲线和相应的动力放大系数谱曲线。通过对反应谱的分析,得到岩塞爆破反应谱的结构响应特性及其影响因素,为水下岩塞爆破的抗振设计提供了可靠的依据,具有较强的实际应用价值和指导意义。更多还原

【Abstract】 According to FenHe Reservoir underwater rock plug blasting monitoring acceleration-time curve,blasting vibration acceleration response spectrum curve and the corresponding dynamic magnification factor spectrum curves were calculated by the convolution method and fast Fourier transform of two response spectrum method of calculation.Through analysis of the response spectrum,we obtained response spectrum response of the structure and its influencing factors.the results provides a reliable basis for Anti-vibration design of the underwater rock plug blasting,and has a strong practical value and significance.更多还原
