爆破震动速度微分与实测加速度的差异分析

Analysis of Difference between Differential Values of Velocities of Blasting Vibration and Actual Measurement Values of Accelerations

在同一测点同时布置了速度和加速度传感器,在同一炮次中,在同样的采样频率情况下,速度值求导应该与实测加速度相吻合或在误差允许范围内。但是,实际情况又较为复杂,两者存在一些差异。本文结合实测工程数据,合理分析原因,得到一些结论。

Arranging velocity and acceleration sensors simultaneously in the same station, in the identical round of holes, under the condition of the same sample frequency, the differential values of velocities should tally with the actual measurement values of acceleration or be in the range of allowable error. But the actual condition is relatively complicated, there is some difference between both of them. Combining with the actual measurement engineering data, analyzing the reasons rationally, some conclusions are drawn.
