[MTT30-01] Utilization of integrated geophysical investigation for near surface surveying
Keywords:Near-surface, Integrated geophysics , S-wave velocity, Resistivity , Geotechnical characterization
The integrated geophysical investigation, we proposed first for the safety assessment of levee systems, is not merely a combined field application of several geophysical methods, but a geotechnical characterization method for the near surfaces. Making use of measured S-wave velocity and resistivity, we assess the safety condition of a levee system on underseepage. Soil types, permeability, and seismic resistance are evaluated.
Case histories of the integrated geophysical investigations successfully applied to levee systems, road embankments, and pavements are presented in association with brief introduction of newly developed field measurement techniques.
