- Abstract:
- Based on the earthquake records of the 2008 M8.0 Wenchuan earthquake recorded by six strong motion stations,we compare and analyze their HVSR spectral ratio results,and study on the effects of HVSR spectral ratio method in analysis site-effects with each seismic phase of the strong motion records.According to the horizontal and vertical Fourier spectrum of each seismic phase,we try to explain the difference and relationship between the strong motion records and microtremor records who using the HVSR spectral ratio method to analyze the site-effects.Finally,we give some suggestions in the use of strong earthquake records with the method of the HVSR spectral ratio.The results show that,due to the inclusion of the source characteristics and path information,the HVSR spectral ratio results of strong motion records and microtremor results have obvious differences,so when using the HVSR spectral ratio in analysis of site-effects caused by strong motion records,It is suggested that the full-wave recording of the strong motron rewrds be sued to study HVSR spetral ratio.
