Discussions and improvements on wave-velocity measuring method in seismic safety evaluation
With Integrated source-receiver device, the method of reading arrival time directly for first arrival wave is usually adopted to test drills shear wave-velocity nowadays, which caused the value of shear wave-velocity can not acquire precisely. A method is proposed as waveform recognition in prime, accurate the time of first arrival shear wave, which can effectively judge the shear wave phase in waveform, then obtain shear wave velocity by testing the arrival time of shear wave, greatly increases the accuracy of waveform identification and wave velocity. It is proved to be a practical method in present engineering practice
