Methodological procedure for applying geophysics to geotechnical studies in Luanda City, Angola

Abstract

The use of the surface wave’s analysis in its passive and active variants was jointly assessed by the shallow seismic refraction. It allows determining dynamic parameters from the longitudinal and transverse velocities, obtained from seismic methods. For the first time, based on the performance of seismic wave velocities, the soils of Luanda city in Angola are characterized and it is demonstrated that a group of seismic methods formed with the multichannel analysis of surface waves and the shallow seismic refraction in its variant 2D MASW, allows greater continuity in the geotechnical characterization of soils.
