露天矿周边民房爆破振动响应的频率特征分析
|
摘要
利用多元线性回归方法建立了综合速度及频率影响的民房爆破振动衰减规律方程,并提出了回归效果检验方法。实测结果分析表明,速度-频率回归公式比传统单一速度回归公式预测精度提高了4%,进一步验证了频率对于建(构)筑物爆破振动响应的重要性,对我国露天矿山安全生产起到很好的指导意义。
Based on multivariate linear regression analysis,attenuation equations were established for blast-induced vibration of residential house influenced by velocity and frequency,and a method was proposed for testing regression effect.The results analysis showed that the accuracy of prediction with velocity-frequency regression equations is 4% higher than that with single-velocity regression equation.It is further verified that frequency is very important in the analysis of building response to blast-induced vibration.This conclusion will be significant in guiding safety production in open-pit mine.
