基于量纲分析的爆破振动频率公式
|
摘要
本文采用量纲分析法,建立了影响爆破振动频率各物理量之间的函数关系,并结合瀑布沟水电站爆破振动的实测数据进行回归分析。在浅孔爆破和深孔爆破的条件下讨论了振动频率的规律,并建立起特定条件下的爆破振动频率的预测公式。为爆破振动频率衰减规律的研究和对类似爆破工程进行主频率预测提供了理论和实际依据。
Based on the dimensional analysis method,the function relations among all the physical quantities those impact the blasting vibration frequency are establish,and then the regression analysis is made in combination with the actual measured blasting vibration data from the construction of Pubugou Hydropower Station.Furthermore,the law of the vibration frequency is discussed under the conditions of both the shallow hole blasting and deep hole blasting,with which the prediction formula for the blasting vibration frequencies under the particular conditions is established;which provides a theoretical and practical basis for the study on the attenuation law of the blasting vibration frequency and the prediction of the principal frequency concerned for the similar projects.
