Assessing Climate Effects on Railway Earthworks Using MASW [PDF]

Proceedings, 2014
Many parts of the UK’s rail network were constructed in the mid-19th century long before the advent of modern construction standards. Historic levels of low investment, poor maintenance strategies and the deleterious effects of climate change have resulted in critical elements of the rail network being at significant risk of failure.

Comparing Shear-Wave Velocity Determined by MASW with Borehole Measurement at Merapi Sediment in Yogyakarta

International Journal of Technology, 2017
Next generation ground motion prediction models use shear-wave velocity over the top 30 m of subsoil (VS30) as an important assessment parameter of seismic ground surface motion.

On the Efficiency of the Multi-Channel Analysis of Surface Wave Method for Shallow and Semi-Deep Loose Soil Layers

International Journal of Geophysics, 2010
The multi-channel analysis of surface waves (MASWs) method was used to obtain the shear wave velocity variations through near surface (depth < 30 m) and semi-deep (30 m < depth < 100 m) soil layers in the city of Ottawa, Canada.

Retrieving shallow shear-wave velocity profiles from 2D seismic-reflection data with severely aliased surface waves [PDF]

, 2019
The inversion of surface-wave phase-velocity dispersion curves provides a reliable method to derive near-surface shear-wave velocity profiles. In this work, we invert phase-velocity dispersion curves estimated from 2D seismic-reflection data.

Characterization of the shallow subsurface structure across the Carrascoy Fault System (SE Iberian Peninsula) using P-wave tomography and Multichannel Analysis of Surface Waves

Geologica Acta, 2022
The seismicity in the SE Iberian Peninsula is distributed parallel to the coast in a well-developed strike-slip fracture system known as the Eastern Betic Shear Zone (EBSZ). This work focuses on the characterization of the shallow subsurface structure of
