SEISMIC SHEAR WAVE VELOCITY MEASUREMENTS UTILIZING MULTI ANALYSIS SURFACE WAVES (MASW)
MASW is a seismic method that uses the dispersive nature of surface waves to map the values of shear wave velocities (Vs) in the subsurface. Shear wave velocity is a function of the elastic properties of the soil and rock and is directly related to the hardness (N-values) and stiffness of the materials. In particular, MASW is used in geotechnical for the measurement of shear-wave velocity and dynamic properties, identification of subsurface material boundaries and spatial variations of shear-wave velocity for site classification.
Applications:
Used to map soil and sediment thickness and elevation of subsurface interfaces, such as top of bedrock and stiffness.
Used to determine shear wave velocity or density of a subsurface material, and the presence and location of voids and karst features.
Site Classification.
