Assessing the soil liquefaction susceptibility: s comparative study of CPT and MASW techniques in the aftermath of road failure

International Conference on Road and Rail Infrastructure
The 2020 Petrinja earthquake had far reaching impact on the engineering linear networks, mostly flood protection embankments and road network. Liquefaction, a phenomenon where the saturated soil temporarily loses its strength and stiffness during intense

EFFECT OF SOURCES AND GEOPHONE COUPLING ON MASW SURVEYS

19th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2006
We have used the multi-channel active surface wave (MASW) seismic method to map stratigraphy and bedrock at sites with differing soil and rock characteristics. The purported advantages of using the shear wave velocity field calculated from surface waves to detect, delineate, and/or map anomalous subsurface materials include the insensitivity of MASW to

Linearized Inversion of MASW Data Using Inequality Constraints

Near Surface 2007 - 13th EAGE European Meeting of Environmental and Engineering Geophysics, 2007
Inequality constraint formulation of least squares inversion is a flexible method to insert physical constraints (as well as a priori information) into the inversion process. In MASW (Multichannel Analysis of Surface Waves) inversion this has proved to be useful to stabilize convergence when applied to fundamental-mode dominated data as well as to data

Comparison of the vs30 model and site class based on MASW, microtremor and N-SPT data in the Opak River Basin

IOP Conference Series: Earth and Environment
The utilization of vs30 data offers numerous applications within the geotechnical field, with one of its primary applications being the determination of site class and the microzonation of site class.

MASW surveys in landfill sites in Australia

The Leading Edge, 2013
Multichannel analysis of surface waves (Park et al., 1999), commonly called MASW, is a seismic technique used to map the near-surface S-wave velocity structure. It has been applied to a range of geotechnical engineering problems, such as detection of cavities (Miller et al., 1999), the search for bedrock structure (Carnevale et al., 2005), examining ...

Kars Investigation by Microgravity and MASW Coupling

Near Surface 2006 - 12th EAGE European Meeting of Environmental and Engineering Geophysics, 2006
A geophysical integrated approach for the detection and characterisation of karst structures in an urban environment was experimented. Microgravity was performed for void detection, together with Multi-channel Analysis of Surface Waves (MASW), aimed to the identification of mechanical weakness areas.
