JACOB, JOSEPH (author)Many immersed tunnels have already reached or are about to reach the halfway point of their intended lifespan of 100 years. Around this time, several structural problems were noticed during inspection which have led to performance deterioration and durability issues of the tunnel. Often large- scale maintenance was required to meet the design...master thesis 2022

Kwok, Matthew (author)The 1st Heinenoordtunnel is an immersed tube which has been open for service in the Netherlands since 1969. Over the past 50 years, a large and increasing settlement has been measured along the tunnel alignment. The greatest value of settlement (65 mm) occurs in tunnel element 1 from 1978 to 2018. The maximum differential settlement has reached...master thesis 2022

Pleij, Lodewijk (author)The soil-grout interface friction was measured to be in between 0.0 [kPa] and 14 [kPa]. To measure this friction, a special research method was invented that enabled a tunnel to be recreated. With this setup, any formation could be used. The formation could be created with a hole in the middle which simulated a borehole. Next, by filling and...master thesis 2022

Ophof, Oscar (author)The historic inner-cities in The Netherlands are largely known for their iconic channels and their accompanying quay walls, of which a significant number were constructed over 100 years ago. Due to the limited available space in the sub-surface of the urban environment, a high number of utility lines (i.e. potable water pipes and sewer systems)...master thesis 2021

Ramphal, Vanisha (author)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 achieve very low hydraulic conductivity. Poor...master thesis 2020

Arun Kumar, Anchal Bhaskar (author)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 to predict the excess pore pressure due to vibratory installation,...master thesis 2020

Yang, M. (author)Differential settlement is a big issue for an immersed tunnel. This will lead to large stress concentrations in the tunnel construction, giving rise to local cracking, failure of the construction, leakage, deterioration of exposed rebar, etc. Variety factors will influence it, like the consolidation process, the action time of different loads...master thesis 2020

Vonk, Michiel (author)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 influence of the TBM tail void and its grouting process on the...master thesis 2020

van Overstraten Kruijsse, Femke (author)During construction in urban areas often noise and vibrations are not tolerated. For the installation of the foundation piles in these cases there is often chosen for screwed displacement piles. These piles can be installed without nuisance for the vicinity, but do induce large soil displacements during installation. The soil displacements can...master thesis 2019

Feiz, Marziyeh (author)This thesis investigates the behavior of single and group micro piles under axial tensile loading. Micro piles are small diameter piles consist of grout and steel rebar and they are capable of absorbing tensile loads. By constructing a group of piles the bearing capacity of each pile within a group is less compared to the single pile. The reason...master thesis 2018

Keuzenkamp, Jeroen (author)Cities are growing and more land is reclaimed. Reclamation is the process of creating new land from ocean, riverbeds or lake beds. New land is created by hydraulic placement of sand. The hydraulically placed fills are characterized by low densities and show a high variety in packing throughout the field. The relative density of the fills depend...master thesis 2017

Sinha, T. (author)The developments in the technology and design philosophy since the first immersed tunnel was completed more than a century ago. These developments include, amongst others: the introduction of the Gina rubber gasket between elements; the division of elements into sections divided by flexible joints; various foundation methods; and the transport...master thesis 2017

de Wolf, J.S. (author)This thesis aims to analyse the conservatism in the current Dutch recommendations on the external friction angle 𝛿 of diaphragm walls: 𝛿 = 𝑚𝑖𝑛[𝜙, 20°] (for curved slip surfaces) (CUR/COB, 2010), by means of an experimental investigation. Based on literature, two sources of conservatism are identified: 1) filter cake contamination by excavated...master thesis 2016

Steiner, A. (author)Thermo-active structures, such as energy piles, are used to store and extract heat energy from soil. In areas with seasonal freezing and thawing, such infrastructure is subjected to changes in the soil structure and, consequently, the soil strength. This research investigated the influence of repeated freeze-thaw (FT) cycles and different...master thesis 2016

Hijnekamp, T.A.J. (author)The focus of this research is on samples taken from the return flow. With these samples and within the context of the Marsdiep project it is investigated if Horizontal Directional Drilling (HDD) can be used as a Site Investigation (SI) technique. In the Marsdiep project the feasibility of a pipeline constructed using HDD between the island Texel...master thesis 2016
