英文摘要: GA-based and conventional derivative-based inversion methods were employed to determine Vs profile of subsurface soil layers from array microtremors for two cities in Iran. The applied methods were verified against geotechnical and geophysical data. The results obtained by both GA-based and conventional inversions were in acceptable agreement with results of other Vs profiling techniques. However, the variability of obtained Vs data was smaller at deeper depths indicating more reliability of predictions. Comparison between seismic ground response based on Vs profiles of different methods showed that both GA-based and conventional inversion methods agree more with the seismic downhole method than the seismic refraction technique. © 2020, Springer Nature B.V.
