A review of seismic geophysical testing in Iran for building near-surface velocity models

摘要: Abstract It has long been understood that the near-surface structure of earth affects several aspects civil engineering practice, particularly in seismic applications. Therefore, implementation a competent subsurface exploration program not only addresses need for comprehensive site characterization but also reduces devastating consequences activities. Typical geotechnical practice often relied on combination drilling, situ testing such as standard penetration and cone testing, laboratory field samples. However, geophysical techniques have developed over years to evaluate velocity models proxy stiffness In this regard, methods refraction, reflection, downhole crosshole spectral analysis surface waves (SASW), multichannel (MASW) continued receive increase...
