Multichannel analysis of surface waves (MASW) for offshore geotechnical investigations

Engineering Geology, 2020
Abstract Multichannel analysis of surface wave (MASW) surveys are commonly used onshore to produce shear wave velocity (Vs) profiles. This paper describes its use in offshore geotechnical investigations (underwater MASW - UMASW) where the focus was on the upper 15 m of the sediment profile to aid the design of structures such as marine pipelines ...

Characterizing the Effects of Survey Parameters on Experimental Love Wave Multichannel Analysis of Surface Wave (MASW) Data

Pure and Applied Geophysics, 2021
Rayleigh waves employed in engineering geophysical applications are typically generated by vertical strikes on a metallic plate that serves as a coupler between an active input source (e.g., a sledgehammer) and the ground surface. Seismic surface waves can also be generated with horizontal impacts (i.e., Love waves) using specialized coupling plates ...

Roadside Passive Multichannel Analysis of Surface Waves (MASW)

Journal of Environmental and Engineering Geophysics, 2008
Abstract A 2-D receiver array, such as a cross or circular type, should be used in a passive surface wave survey to provide the most accurate results. It is often not possible to secure such a spacious area, however, especially if the survey has to take place in an urban area.
