Advances in Surface Wave Methods – Cascaded MASW-SASW
Near Surface 2005 - 11th European Meeting of Environmental and Engineering Geophysics, 2005The application of the MASW method in areas that show strong lateral variations in subsurface properties is limited. Traditional SASW may yield a better lateral resolution but the dispersion curves (and thus the subsurface models) obtained with the method may be poor.

Soil Classification Mapping by Vs30 MASW Measurements in Gorontalo City
IOP Conference Series: Earth and EnvironmentThe city of Gorontalo, in the north of Sulawesi Island, has a relatively high potential for earthquake events. This condition is influenced by the meeting of three plates, namely the active subduction zone of the Sulawesi Sea trench, which is subducting ...

Some Practical Aspects Of Masw Analysis And Processing
21st EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2008We use multi-channel analysis of surface waves (MASW) on seismic data in an attempt to test data acquisition parameters and compare those results to reaffirm existing general theoretical recommendations and rules of thumb. Of particular interest were optimum seismic receiver spread size, minimum and maximum receiver offsets and dominant geophone ...

MASW for geotechnical site investigation
The Leading Edge, 2013Multichannel anaylsis of surface waves (MASW) is a seismic surface-wave technique developed specifically for near-surface applications at depths usually shallower than a few tens of meters (Park et al., 1999). Since its introduction in the late 1990s, use of the technique has rapidly increased for two reasons: (1) it provides the ...

Practical Aspects of MASW Inversion Using Varying Density
Symposium on the Application of Geophysics to Engineering and Environmental Problems 2009, 2009We use multi-channel analysis of surface waves (MASW) on seismic data to assess the practical impact of the assumed compressional-velocity and density parameters on the inverted shear-wave velocity results. The practical secondary-parameter impact evaluation was performed on data acquired in the arctic. The ice-sheet compressional-, shear-wave velocity

Higher mode observation by the MASW method
SEG Technical Program Expanded Abstracts 1999, 1999A higher mode (the first overtone) of high frequency (5–30 Hz) surface waves was observed by using the multi-channel analysis of surface waves (MASW) method at three boreholes located in unconsolidated sediments in the Fraser River Delta, near Vancouver, British Columbia.

Uncertainty reduction in MASW inversion and ground response analysis using a-priori information
Geotechnical EngineeringMulti-channel analysis of surface waves (MASW) method is commonly used for estimating the shear wave velocity (Vs) profile of soil and subsequent ground response analysis (GRA). However, the uncertainties from inversion non-uniqueness in MASW testing and

Комплексирование электроразведки ВЭЗ и сейсморазведки MASW
5th EAGE International Scientific and Practical Conference and Exhibition on Engineering and Mining Geophysics, 20091. MASW и ВЭЗ – общая идеология Анализ волновой картины, возникающей при импульсном возбуждении сейсмических колебаний, позволяет построить кривую зависимости скорости распространения поверхностной волны от ее частоты. По своему интегральному характеру она подобна кривым электромагнитных зондирований и может пониматься как зависимость от частоты (f ...

MASW applications for road construction and maintenance
The Leading Edge, 2018Road construction and maintenance are major parts of geotechnical engineering that deal with the stiffness of natural or manmade ground materials. At the earliest stage of new road construction, the ground along the planned route often needs to be characterized in terms of the overall stiffness of the overburden-bedrock system.
