One of the most important engineering parameters for determining the dynamics properties of soil is shear wave velocity, which has a direct ...

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 ...MASW. Selected samples of the inverted Vs models for some MASW profiles in the study site are shown in (Fig. 6). The positions of these profiles are shown in (Fig. 1). The shear-wave velocity varies from 180 m/s to 1000 m/s, reflecting the variations in the composition of the subsurface materials and rock qualities in the proposed construction ...Nov 3, 2017 · Welcome to MASW Menu Toggle. 2023 Brochure Menu Toggle.
