| 摘 要： | 爆心距是影响爆破振动强度的重要因素,对爆心的准确定位可获取更接近实际情况的爆心距,从而更加准确的对爆破振动质点速度峰值进行预测.基于现场的实测爆破振动信号,利用MATLAB软件编制程序,进行双谱时延估计仿真试验,验证了此方法对于爆破振动信号时延估计的可靠性.然后利用该方法确定不同传感器接收的爆破振动信号延迟时间,采用正...

| Abstract: | The distance to blast center is an important factor of impacting on blasting vibration,the exact location of blast center could obtain the actual distance to blast center,which is more accurate of predictting the peak particle velocity of blasting vibration.Based on the monitored vibratioin signals on site,and using the development process of MATLAB software,the bispectrum time delay estimation is simulated to prove the reliability of this method for blasting vibration signals delay estimation.Then the sign... |
