Concrete Flow in Diaphragm Wall Panels: A Full-Scale In-Situ Test

Flow processes, taking place during the concreting of diaphragm wall panels (D-wall panels), are of great importance for the quality of the wall. During this phase, the bentonite, present in the excavated trench, should be completely replaced by concrete in a controlled way. In literature several cases are described in which this process...

Observational Method, Case A2 Maastricht

The A2 tunnel in Maastricht has been built within a dry building pit with a maximum depth of 22 meters with sheet pile walls, suspended in a cement bentonite trench supported by struts at 2 to 4 levels. Dewatering is done by deepwells. The excavation reaches into Limestone layers so the maximum mobilized passive resistance of the sheet pile wall...

Geotechnical Risks in a Deep Building Pit in The Hague’s Old City Centre: Project Veenkade Case Study of the Restoration of an Old Canal and a New Underground Parking Garage

In The Hague, a 2 storey parking garage was built beneath a reinstated canal at the Veenkade with 160 parking places. The canal and the parking garage were installed at minimum 3 - 6 m distance from old houses with a shallow foundation by means of a 10 m deep building pit. A risk analysis was undertaken and major risks were identified, resulting...

Small incidents, big consequences. Leakage of a building pit causes major settlement of adjacent historical houses. Amsterdam North-South metro line project

The construction of the North-South metro line project in Amsterdam (the Netherlands) is ongoing for the last five years and until recently suffered no major construction incidents. In the summer of 2008 two leakages occurred in one of the building pits of the deep stations. These leakages caused major settlement of a number of historical houses...

Settlement during vibratory sheet piling

During vibratory sheet piling quite often the soil near the sheet pile wall will settle. In many cases this is not a problem. For situations with houses, pipelines, roads or railroads at relative short distance these settlements may not be acceptable. The purpose of the research described in this thesis is to develop a model that is capable of...

Delft Beheerst Ondergronds Eindrapportage

De Spoorsingelvariant: Een ontwerp van de tunnelverbinding tussen de metro en de RandstadRail in het centrum van Rotterdam

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...

Alternatieven voor bouwkuipwanden: Diepwand versus stalen damwand

De Noord/Zuidlijn is een metroverbinding tussen Amsterdam-Noord en Amsterdam-Zuid welke deels bovengronds en deels ondergronds zal worden aangelegd. Indien alles volgens plan verloopt zal de Iijn in 2005 operationeel zijn. Het ondergrondse deel van de lijn zal worden geboord. De tunnelbuis dient hierbij zo ver mogelijk verwijderd te blijven van...

Oostelijke inrit van de Piet Heintunnel

In Amsterdam worden de voormalige havengebieden langs de zuidelijke U-oever herontwikkeld tot moderne woon- en werklocaties. De ontsluiting van deze zone zal gebeuren door de zogenaamde U-boulevard. Deze U-boulevard sluit aan de westkant van Amsterdam op de Ringweg (AIO) West aan, bij Sloterdijk. Aan de oostkant van Amsterdam sluit de U...
