摘要
Microtremor survey technology is a new survey technology which developed on the basis of traditional microtremor depth sounding by Doc.XU Pei-fen and others of Institute of Geology and Geophysics of Chinese Academy of Science in recent years,it has been used in many exploration fields.This technology is use seismic detector to receive the waves from every direction on surface,take the Rayleigh wave dispersion curves by SPAC method and get S-wave speed by inversion.The technology won’t be influenced by magnetic and noise,the survey depth is deep.Although there is some limitation now,the advantages shows this technology will be a promising new method.
