Wiersma, Jolt (author)The performance of a city is dependent on the performance of its infrastructure. As a result, the surface-level world is inseparable from the subsurface world. However, cities around the world are facing a shortage of available space both aboveground and belowground. The existing urban fabric has over time become unfit for the addition of new...master thesis 2023

van Marrewijk, Chris (author)Although the concept of a submerged floating tunnel (SFT) originates from the early 1900s, the cross-section is always assumed to be circular or rectangular. In this research, it is investigated whether this assumption is valid. In order to find the optimal cross-section, the optimization process is split into two targets. The first targets aims...master thesis 2020

Vicca, Elke (author)Hyperloop is a high-speed transportation mode which operates by sending magnetically levitated capsule-like vehicles through a near vacuum tunnel. Due to the reduced air resistance and friction, speeds exceeding those of modern aircraft should become possible. When the system is moved underground,<br/>the stability of vehicle vibrations may...master thesis 2019

van Ramshorst, Justus (author)Near-surface wind speed is typically only measured by point observations. The so-called Actively Heated Fiber-Optic (AHFO) technique, however, has the potential to provide high-resolution distributed observations, allowing for better understanding of different processes. However, before it can be widely used, its performance needs to be tested...master thesis 2018

Vlemmix, Christian (author)Since both the aircraft and wind energy sectors are experiencing rapid growth, improvements must be made in terms of noise reduction as to enable growth whilst fulfilling the restrictions on noise pollution. An open-section vertical wind tunnel with an anechoic test chamber has recently been constructed at the Delft University of Technology, in...master thesis 2017

Koning, W.J.F. (author)Experimental techniques to measure rotorcraft aerodynamic performance are widely used. However, most of them are either unable to capture interference effects from bodies, or require an extremely large computational budget. The objective of the present research is to develop an XV-15 Tilt Rotor Research Aircraft rotor model for investigation of...master thesis 2015

Heemskerk, P.W.M. (author), Horsten, B.P.M. (author), Kramer, R. (author), Korevaar, T.J.A. (author), Van der Valk, R.E.A. (author)Cartagena is one of the main touristic attractions of Colombia with its good conserved colonial city centre. The city also has an important contribution to the economic growth of Colombia, because of its big port and its beneficial location towards the Panama Channel. However, Cartagena is suffering from problems with the accessibility of...student report 2014

Bergsma, J.G. (author)The thesis aims to find the changes in design and execution to immersed tunnels in subarctic regions. The Orlovsky Tunnel in St. Petersburg serves as a case study. The Orlovsky tunnel is a 1600 m tunnel in a rapid flowing river. the ice regime of the Neva River is characterized by frazil ice, which causes hanging ice jams and anchor ice....master thesis 2013

Van Aken, S. (author)This thesis focuses on assessing the crack width and durability at the outside of an immersed tunnel in case of fire inside the tunnel. Previous research (for instance Nieman [20]) addressed only the heating phase of a tunnel while also the inevitable cooling phase may have a large influence on the crack width. A user supplied code was written...master thesis 2012

Van Kessel, L.A.J. (author)The tunnel boring process introduces soil settlements. Damage to nearby building could occur if settlements become too large. A reliable damage prediction model is necessary too asses the risks of damage to tunnel induced settlements. A widely used method for damage prediction is the Limiting Tensile Strain Method (LTSM). The LTSM models a...master thesis 2012

Schaap, D.J. (author)In the research of the territory of Liverpool, the in-between and Manchester an artefact of the Industrial Revolution appeared. The tunnels of Liverpool (the artefact) have been re-activated by the implementation of a series of interventions. These underground structures, each formed by a specific structural and spatial pattern, have the ability...master thesis 2010

Huneker, S.L. (author)In Amersfoort levert de A28 aan de oostkant van de stad grote overlast op voor de bewoners van de Verdiweg en achterliggende bebouwing. De toenemende geluidsoverlast en luchtverontreiniging als gevolg van een groeiend verkeersaanbod belemmeren niet alleen de groei van de stad, maar ook een verbreding van de weg zelf, waardoor de bestaande...master thesis 2010

Kouwenberg, P.E.D.M. (author)To reduce traffic problems and to improve the social climate in Maastricht a tunnel will be constructed for the A2 motorway. The tunnel will be construction with the cut-and-cover method. Before the constructions starts first a ground improvement campaign is performed. Afterwards sheet pile walls will be installed in cemented slurry trenches and...master thesis 2009

De Jong, P.J. (author)Following from the increasing demand for "Design & Construct" and property development projects, Ballast Nedam is looking for a methodology that can support the decision making process in order to create a good competition in the new market. The objective of this study is to investigate the application of a Decision Analysis in early phases of...master thesis 2000

De Jong, D.J. (author)Certain goods have properties that may cause severe effects in case of an accident during transport. The most striking events are the occurrence of fire and explosions. Since tunnels are isolated environments, many casualties and severe damage are to be expected in case of an explosion. Although the probability for such an event is rather small,...master thesis 2000

Berkers, K.H.F. (author)Het doel van dit onderzoek is tweeledig. Het eerste doel omvat het inventariseren van de verschillende soorten hinder voor de korte en de lange boortunnelvariant. Het tweede doel omvat het analyseren van de geconstateerde knelpunten in het Referentieontwerp en het uitwerken van een knelpunt met grote waterbouwkundige relevantie. In deelrapport I...master thesis 2000

Kruizenga, H.A. (author)Uit het 'Tweede Structuurschema Verkeer en Vervoer' blijkt de aanleg van een hoogwaardig vervoerssysteem voor de middellange afstanden in de Zuidvleugel van de randstad noodzakelijk. De oplossing wordt gezocht in het invoeren van een lightrailsysteem, genaamd de RandstadRail, op het traject tussen Den Haag en Rotterdam. De ontwikkeling van de...master thesis 1999

Everaars, M.J.C. (author)Het aanleggen van een station, inclusief toegangen, in aansluiting op geboorde tunnels in stedelijk gebied, levert, met de open bouwwijze en de bouwwijze vanaf het maaiveld, veel hinder op voor de bestaande bovengrondse infrastructuur en de omwonenden. Om de bovengrondse hinder te minimaliseren, is een ondergrondse uitbouwmethode onderzocht. Het...master thesis 1999

Van der Eijk, R.W. (author)De snef groeiende luchtvaartsector in Nederland krijgt te maken met ruimtegebrek. Elk jaar stijgt het aantal vliegbewegingen en alle prognoses geven dezelfde explosieve groei voor de komende 15 tot 20 jaar. Het ruimtegebrek manifesteert zich in eerste instantie in de vorm van geluidshinder. Het grootste deel van alle vliegbewegingen in Nederland...master thesis 1999
