In this episode NGI’s Georg H. Erharter and Tom F. Hansen talk about rock mass classification for tunnel construction and other applications. We start with a look back into early developed rock mass classification systems and then move forward up to state of the art applications of machine learning for rock mass classification and characterization that can be used today and perhaps will shape the future of this field.

SPEAKERS

Georg H. Erharter and Tom F: Hansen are both engineering geologists working in the rock engineering department of NGI. Tom F: Hansen has substantial practical experience ranging from rock engineering in coal mining at Svalbard up to engineering geological work for the Norwegian public railway authority. Today, he is finishing a PhD about the application of machine learning for rock engineering. Georg H. Erharter has brought practical experience from large alpine tunnel projects such as the Brenner- or Semmering Base tunnels to NGI and today is working in both engineering geological consultancy and research. He holds a PhD in Civil Engineering where he dealt with machine learning for geotechnics, and he is generally engaged with using modern technology to solve long standing problems of the field.
