Masw

Product from MASW Surveys Final product from an MASW survey is the subsurface variation of shear-wave velocity (Vs) in 1-D (depth) (Figure 1), 2-D (depth and one surface direction) (Figure 2), and 3-D (depth and two surface directions) (Figures 3 and 4) formats. The shear-wave velocity (Vs) most closely .

A joint analysis of down-hole (DH) and multichannel analysis of surface waves (MASW) measurements offers a complete evaluation of shear wave velocity profiles, especially for sites where a strong lateral variability is expected, such as archeological sites. In this complex stratigraphic setting, the high “subsoil anisotropy” (i.e., sharp lithological changes due to the presence of ...
