[HTT17-P02] Integration of surface and subsurface geoinformation around PWRI Tsukuba Site using 3D geoscientific modelling software
Keywords:Near surface, Log data, Geophysical data, 3D model, Geoinformation, PWRI
The constructed 3D geoscientific model is characterized as integration of surface and subsurface geoinformation, especially as consisting of 2D geophysical sections and 1D logging profiles as the essential subsurface geoinformation, which are helpful to reconstruct subsurface 3D layered model. In addition, geophysical information is quite useful to evaluate the quality of geotechnical boring log data and eliminate unreliable or fabricated data embedded in boring log data.
The software we used, which has been widely utilized in geoscientific research field, was powerful and cost effective for building 3D models of the near surfaces. On the other hand, the system cannot import SEGY format profiles directly. An authorized or a standard near surface 3D visualization system is required as a platform which has the ability not only to easily import and but also to process various types of geophysical information along with surface geospatial information.
