Differential Inversion of Surface Wave Methods: Proposition of Diagram Distance as Inversion Data
Autor: D. Leparoux, M. Le Feuvre, Odile Abraham, A. Wang
Publikováno v: NSG2020 26th European Meeting of Environmental and Engineering Geophysics.
Summary Seismic methods based on Surface Waves are widely used in geophysics to characterize mechanical parameters of the subsurface as well as the civil engineering infrastructures. And for natural risk issues, environmental monitoring is more and m

Evaluation of Dispersion Diagrams Distances Based on Usual Histogram Analysis for the Surface Wave Difference Inversion
Autor: A. Wang, D. Leparoux, M. Le Feuvre, Odile Abraham
Publikováno v: 1st Conference on Geophysics for Infrastructure Planning Monitoring and BIM.
Summary In some recent geophysical monitoring studies, researchers have proposed a method of difference inversion, which means taking the difference between data into inversion process. It overcomes the crucial problem of the initial model for local

Autor: Philippe Côte, Yann Capdeville, D. Pageot, M. Le Feuvre, D. Leparoux
Publikováno v: Journal of Applied Geophysics
Journal of Applied Geophysics, Elsevier, 2020, 172, pp.103841. ⟨10.1016/j.jappgeo.2019.103841⟩
International audience; Seismic surface waves analysis methods have been widely developed and tested in the context of subsurface characterization and have demonstrated their effectiveness for sounding and monitoring purposes. Given their efficiency,

Impact of Small Shear Wave Velocity Variations on Surface Wave Phase Velocity Inversion
Autor: Odile Abraham, M. Le Feuvre, A. Wang, D. Leparoux
Publikováno v: 24th European Meeting of Environmental and Engineering Geophysics.
Summary Surface wave methods have attracted a lot of geophysicists’ attention for the purpose of monitoring civil engineering structures, because they represent the most energetic part of the seismic signal, and contain information on shallow media

Monitoring of the Tidal Response of a Sea Dike Using Sea Waves as Seismic Noise
Autor: Anaëlle Joubert, M. Le Feuvre, Philippe Côte
Publikováno v: Proceedings.
Ambient seismic noise has long been considered as a nuisance for the analysis of seismograms. For some years now, it has shown a great potential for monitoring various geological objects with high accuracy. Here, using ambient seismic noise generated

Statistical redundancy of instantaneous phases: Theory and application to the seismic ambient wavefield
Autor: Ianis Gaudot, M. Le Feuvre, Martin Schimmel, Eric Beucler, Antoine Mocquet
Publikováno v: Digital.CSIC: Repositorio Institucional del CSIC
Consejo Superior de Investigaciones Científicas (CSIC)
Geophysical Journal International
Geophysical Journal International, Oxford University Press (OUP), 2016, 204 (2), pp.1159-1163. ⟨10.1093/gji/ggv501⟩
In order to detect possible signal redundancies in the ambient seismic wavefield, we develop a new method based on pairwise comparisons among a set of synchronous time-series. This approach is based on instantaneous phase coherence statistics. The fi

Refined experimental studies for improving the reduced-scale physical modeling of seismic subsurface measurement
Autor: Philippe Côte, D. Pageot, Yann Capdeville, Olivier Durand, M. Le Feuvre, D. Leparoux
The potential of experimental seismic modeling at reduced scale is explored since several years because it provides an intermediate step between numerical tests and geophysical campaigns on field sites. The MUSC system is designed as a reliable tool,

Passive multi-channel analysis of surface waves with cross-correlations and beamforming. Application to a sea dike
Autor: M. Le Feuvre, D. Leparoux, Philippe Côte, Anaëlle Joubert
Publikováno v: Journal of Applied Geophysics
Journal of Applied Geophysics, Elsevier, 2015, 114, pp.36-51. ⟨10.1016/j.jappgeo.2014.12.014⟩
We introduce the use of cross-correlations in the passive multi-channel analysis of surface waves (MASW), and report an improvement in the determination of subsurface shear velocities from ambient seismic noise. Velocities are measured from phase-shi
