摘要
为控制隧道爆破振动效应产生的危害,采用回归分析法对爆破振动的传播规律进行研究。首先采用一元线性回归与二元线性回归对爆破振动实测数据进行分析,确定不同影响因素下萨氏公式的相关参数,进而研究隧道爆破振动的传播规律,然后计算不同爆心距对应的爆破最大段药量,最后通过爆破振速峰值分析来判断隧道爆破的安全程度。研究结果表明,该隧道爆破振动危害在控制范围之内,不会对地表建筑物造成影响。
In order to control the hazards of the tunnel blasting vibration effects, regression analysis is applied in the study of blast vibrationg propagation law. Firstly, the actual measured data of the blasting vibration was analyzed by the unary linear regression method and binary linear regression method. The relevant parameters of the Sadovg formula were defined with consideration on different factors. And then the propagation law of the tunnel blasting vibration was studied. Secondly, the maximum segment advising dose which corresponds to the blast center distance was figured out. Finally the safety degree of tunnel blasting can be determined by the peak value analysis of the blast vibration. The results show that the hazards from the blast vibration effect are under the control and it will not do any damage to surface structures.
