Senior Consultant at SRK Consulting

A couple of weeks ago, I had the pleasure of attending #ISC7 in Barcelona, where the SRK Consulting team presented various interesting developments. I was involved in three papers presented in the congress: One work, in collaboration with Joe Rola CPEng, Mauro Giuliano Sottile, Nicolás Alejandro Rivas, and Alejo O. Sfriso, detailed the development of a 3D ground model using Leapfrog software. This model was created using data from over 200+ CPTu soundings, 30+ boreholes, and 30+ test pits.

The results are exciting, with soil layers being identified very well in a highly computationally efficient manner.

Our study compared the widely-used Boulanger & Idriss (2014) method with the novel approach by Saye, Olson, and Franke (2021). By analyzing CPTu data from various tailings storage facilities around the world, we found that the new method offers a more robust analysis, particularly for fine tailings.

It was nice to get back to Barcelona after so many years. #isc7, #groundmodel, #leapfrog, #machinelearning, #dbscan, #hdbscan, #liquefaction, #tailings
