Abstract
The paper examine and describe the hypothesis that ”the soil spectroscopy is a useful technique in the analysis of engineering index properties of a geologic material, which might lead to a better understanding of the deposit and a full understanding of its engineering geology”. Specifically, it was investigated whether spectral techniques can be used to determine material provenance and geotechnical conditions. In the Visible/Near-Infrared (VNIR) and Short Wave Infrared (SWIR), many materials absorb radiation at specific wavelengths, allowing their identification by the position and character of absorption features. This helps in introducing the scientific principles of visible and near reflective spectroscopy with relation to the engineering index properties of a geologic material. The methodology used involves the use of Laboratory investigations which provides valuable information in the geotechnical interpretation and laboratory spectral techniques. This can allowed a study area to be characterized in terms of geology, geomorphology, geotechnical and spectral properties. This paper will therefore present an overview of the visible through NIR (Near infrared) laboratory spectroscopy with a brief summary of theory and application. The research also shows how reflective spectroscopy is as an extremely useful and efficient technique that can be use for the analysis of the engineering properties of a geologic material. The study tries to investigate the effectiveness of soil spectroscopy method on the London Clay Formation.
