Borehole / Ground penetrating radar research opportunities

Click For Summary

Discussion Overview

The discussion focuses on research opportunities in ground penetrating radar (GPR) and borehole radar, particularly in the context of data analysis, processing, and interpretation. Participants explore the applications and limitations of these geophysical techniques in subsurface surveys and geotechnical investigations.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks information on gaps in current GPR and borehole radar research related to data analysis and interpretation.
  • Another participant notes that geotechnical exploration is a key application of GPR and borehole radar, highlighting its use in locating buried objects and assessing soil properties.
  • A participant describes GPR as a technique that utilizes electromagnetic waves to image subsurface structures, mentioning alternative methods like seismic waves for subsurface exploration.
  • One participant expresses skepticism about the reliability of geophysical methods compared to in-situ methods, suggesting that geophysical data is often seen as preliminary and insufficient for critical applications like foundation design.
  • A later reply references a paper discussing the limitations of geophysical methods in geotechnical subsurface exploration.

Areas of Agreement / Disagreement

Participants express differing views on the reliability and applicability of geophysical methods versus in-situ methods, indicating a lack of consensus on the effectiveness of GPR and borehole radar in certain contexts.

Contextual Notes

Some participants highlight the need for improved data analysis techniques in GPR research, while others question the overall reliability of geophysical methods in comparison to traditional exploration techniques.

Hi Members

I am preparing to do a presentation on possible research opportunities in ground penetrating radar before an Industry and academic audience. Anyone with information as to what is lacking or needs improvement in current BH or GPR research in the context of Data analysis (processing and interpretation)?

you mean general Geotechnical exploration tools?
 
Research opportunities in gpr/borehole radar

Yes, Geotechnical exploration is part of applications of ground penetrating radar and/or borehole radar- This is actaully a specialised geophysics technique used for the following:

Subsurface surveys eg finding buried landmines, minerals, cavities, underground water, soil property investigations, even geotechnical investigations such as bridge decks, tunnel investigations, concrete integrity assessment

GPR/Radar based on timing and imaging electromagnetic waves that reflect on interfaces or objects with a change of electrical properties compared to surrounding medium. There are several other techniques eg those that use artificial shock/sesmic waves
to explore the Earth subsurface

Thanks

I am not familiar with this geophysics procedure. In general, in large scale projects it is preferred digging holes, method with thin walled tubes, rotatory methods for rocks, and the like (in-situ methods) over geophysical methods (sismic, electric resistivity, magnetic and/or gravimetric).

I am not saying geophysical methods are not used. They are, mainly for preliminary research, but the information they provide is not seen as reliable as others and is never enough for a project (such as foundation design).
