The prize is established by The Ingeokring. And this year’s prize goes to:

Pascale Lamens
MSc Geo-Engineering, CEG, Delft University of Technology

For her thesis:
“Pile installation in submerged sandy slopes: Assessing liquefaction-induced instability”.
And was defended in October 2017.

The Ingeokring congratulates Pascale with here amazing work! Her name has been added now to the Ingeokring’s Hall of Fame.

Report on the RijnlandRoute excursion in Leiden on May 17th 2019

On Friday May 17th 2019, the Ingeokring organized an excursion to the RijnlandRoute in Leiden.

After all the participants arrived, Anne Bäcker (Arthe C&S) started her presentations: first, about the design of the tunnel, its concrete segments, and the cross passages, all this in relation to then challenging geology of the area. Furthermore, she gave us a tour guide before entering the site of the TBM launch shaft.

But before we actually went to the launch shaft site, we had an archaeological intermezzo: René Isarin ( RijnlandRoute / Provincie Zuid-Holland) explained why and how the Romans established in the Leiden area 2000 years ago. This is due to the archaeological excavations in the sandy deposits along the river Old Rhine: many objects, and rudiments of Roman residences, fortresses, and road sections have been discovered.
He described how the Romans set up their settlements and how they build their roads. For example: the majority of their roads along the Limes border (along the Dutch part of the Rhine) have been strengthened with oak trees dated from exactly the same year! This indicates an early demonstration of a design process concerning harvesting trees and logistical challenges.
