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 harm of tunnel blasting vibration effect, the propagation law of blasting vibration is studied by regression analysis method. Firstly, the data of blasting vibration were analyzed by the linear regression and binary linear regression, and the relevant parameters of the equation under different influencing factors were determined. Then the propagation law of tunnel blasting vibration was studied, and then the maximum segment of blasting Finally, the peak blasting vibration velocity analysis to determine the safety of tunnel blasting. The results show that the blasting vibration of the tunnel is within the control range and will not affect the surface buildings.
