In 2017 the Dutch national standardization institute (NEN) released a new version of the National Annex to NEN-EN 1997-1 Eurocode 7, including revised reduced pile base factors. This has a significant impact on the dimensions of pile foundations. Consequently, in situ load tests

The conceptual design of a graving dock
Using Life Cycle Analysis to reduce the carbon footprint of a graving dock for Damen Harlingen
An extensive Life Cycle Analysis (LCA) is used to determine the efficiency in reducing the carbon footprint of a graving dock. Firstly by identifying the hotspots in a base design, and then by comparing the various design alternatives. The focus is on reducing the amount of reinf

Circular building foundations
A structural exploration of the possibilities for making building foundations contribute to a circular economy
This research investigated how traditional foundations of buildings can become circular and thus contribute to a circular economy. The current linear take-make-dispose economy results in waste, exhaustion of finite natural resources and environmental degradation. A circular econo

Grouting the tail void
Analysis of the tail void grouting process at the North/South line
To fight increasing traffic in city centres, tunnelling can be used to move traffic under the surface of the busy city. However, to prevent damage to the surrounding buildings, the settlements induced by the tunnelling should be kept to a minimum. This thesis researches the influ

The Impact of micro-tunnelling on adjacent pile foundations
Numerical modelling of micro-tunnel excavation in PLAXIS
A series of finite element simulations via PLAXIS were carried out to investigate the effects of micro- tunnelling on nearby pile foundations. A numerical model concerning the large diameter tunnel boring machine was first established based on identical properties of the centrifu

Energy piles are getting more attention for their sustainable and economic potential. The fluid pipes are integrated in the foundation piles, which makes it cost-attractive, but also relatively new to the Dutch geotechnical industry. By lowering the temperature limit of the anti-

This research addresses the complex challenge of mitigating uplift within a water-retaining system, specifically focusing on the Valmeer Energy Storage Lake (ESL), an integral part of the DELTA21 project. The need for rapid emptying of the ESL during storm surges, often within a

Vibratory installation of piles and casings can be extremely economical, therefore the contractors prefer pile driving. When compared to impact pile driving, vibratory pile driving generates less noise but this installation method is still fraught with uncertainties (Rausche 2003

Cement-Bentonite
(CB) walls are low permeability vertical cut-off barriers that are mainly used
to prevent groundwater flow and isolate contaminated areas. The hydraulic
performance of the CB walls depends on the flow rate (discharge) through the
wall. Therefore, the walls must a

Vibratory installation of sheet piles is the most economic and suitable for the sandy soil because of its mechanism. However, the process induces excess pore pressure in saturated conditions leading to subsidence. This research focuses on the development of a tool-based solution

This master thesis aims to do a detailed conceptual design of a tunnel to connect the road A15 and A12, which will cross the Pannerdens canal ( represented by red color in figure 1.1) and a deep comparisonwith the bridge plan solution which has already been adopted by the governm
