Distributed acoustic sensing (DAS) is a novel seismic observation system developed in
recent years that can realize ultrahigh density observations and has attracted extensive …

The frequency-dependent properties of Rayleigh-type surface waves can be utilized for
imaging and characterizing the shallow subsurface. Most surface-wave analysis relies on …

The shear-wave (S-wave) velocity of near-surface materials (soil, rocks, pavement) and its
effect on seismic-wave propagation are of fundamental interest in many groundwater …

Civil and structural engineering consultants engaged in quality control or investigations of
hardened concrete need a comprehensive resource that explains the methods of …

Traditional approaches of using dispersion curves for S-wave velocity reconstruction have
limitations, principally, the 1D-layered model assumption and the automatic/manual picking …

Simulated annealing was used to invert fundamental and higher-mode Rayleigh wave
dispersion curves simultaneously for an S-wave velocity profile. The inversion was applied …

Recent field tests illustrate the accuracy and consistency of calculating near-surface shear
(S)-wave velocities using multichannel analysis of surface waves (MASW). S-wave velocity …

Near-surface geophysics uses the investigational methods of geophysics to study the nature
of the very outermost part of the earth's crust. Man interacts with this part of the earth's crust …

The multichannel analysis of surface wave (MASW) method has been effectively and widely
used to determine near-surface shear-wave velocity. Horizontal resolution of the MASW …

We present a new algorithm for calculating an image of dispersive energy in the frequency-
velocity (fv) domain. The frequency decomposition is first applied to a shot gather in the …
