WebABSTRACT We have applied a combined workflow of frequency-dependent traveltime tomography (FDTT) and full-waveform inversion (FWI) to 2D near-surface P- and SH-wave seismic data to detect a known target consisting of a buried tunnel with concrete walls and a void space inside. FDTT inverted the P- and SH-wave picked traveltimes at 250 Hz to … http://www.tcsurg.org/article/10.3760/cma.j.cn511434-20240208-00050

WebJan 1, 2024 · Comparison of combined 2D SH full waveform inversion strategies. In order to fit the dominant Love-waveform and first arrival waveform, we test different combinations of the “classical” FWI strategies mentioned in the last paragraph. The FWI result of one part is the initial model for the next. 5.1. WebMar 10, 2024 · The detection of cavities with geophysical methods is a challenging task for which a general approach has not yet been found. We have found that viscoelastic SH full-waveform inversion (FWI), focusing primarily on reflection events, is able to accurately locate the position of cavities, areas of decompacted sediments, and, more generally, …
