Portable Seismic Acquistion System (Psas) For Pavement Masw

15th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2002
A seismic method (e.g., surface- or body-wave method) has been often used in pavement engineering to evaluate such critical constructional parameters as the E-modulus and Poisson’s ratio. Conventional method usually uses one or two-channel recording device (e.g., dynamic signal analyzer) for data acquisition whose cost is by no means trivial.

Application of MASW in road failure investigation

Arabian Journal of Geosciences, 2011
Multichannel analysis of surface waves (MASW) survey was conducted to measure shear wave velocities in order to ascertain the likely causes of road failure along LASU-IBA expressway in Alimosho local government area, Lagos, Nigeria. MASW data were acquired along the express road.

Optimal Spread Design for Passive MASW

Proceedings, 2011
The passive surface wave method has the potential to reach investigation depths significantly greater than active sources and can be effectively used in very noisy settings. In this study the optimal spread layout and orientation is investigated and determined that would allow surface wave penetration deep enough into the bedrock to permit studies of ...

EVALUATING LIQUEFACTION SUSCEPTIBILITY THROUGH HVSR AND MASW METHODS: A CASE STUDY IN MAMUJU, WEST SULAWESI, INDONESIA

Rudarsko-geološko-naftni Zbornik
The 2021 Mamuju earthquake (Mw 6.2) highlighted the region's high vulnerability to liquefaction due to its proximity to active tectonic zones, as well as the presence of Holocene alluvial deposits, unconsolidated sedimentary formations, and water ...

Correlation between SPT, CPT and MASW

International Journal of Geotechnical Engineering, 2010
AbstractGeotechnical engineers use in situ tests for site characterization. In this paper, an attempt has also been made to evaluate geotechnical site characterization by carrying out in situ tests using different in situ techniques such as standard penetration test (SPT), cone penetration tests(CPT) and multi channel analysis of surface wave (MASW ...

MASW Survey Using Multiple Source Offsets

22nd EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2009
Although it is generally known that the active MASW method tends to average out the near-field effect of surface waves through the slant-stack process implicitly incorporated in dispersion imaging and therefore one optimum source offset (X1) is usually employed for a given survey, a long source offset to ensure recording of long wavelengths can ...
