During the construction of the Nieuwe Sluis Terneuzen, tubular piles and sheet piling were installed in the embankments of the water barrier. Due to the presence of glauconite-containing sand and Boom Clay, heavy piling and vibration work was involved. Slope stability had to be maintained during the work. To this end, piling tests were carried out, prediction models were drawn up, vibrations and pore pressure were monitored during execution and control measures were taken. This enabled the work to be carried out in a controlled way. Full article
Geotechnical risk analysis Westsluis
M. Hinborch, A.V. van Uitert, E. Dekker, A. Verwij, Geotechnical Special New Lock Terneuzen, March 2021, page 53
The construction work for the New Terneuzen Lock will affect the existing Western Lock. Through the use of a geotechnical risk analysis in the design phase and extensive monitoring in the execution phase, taking into account the natural deformation bandwidth, it is ensured that deviations are detected early and no damage will occur.
