De Jong, M. (author), Annema, J.A. (author)De meeste grote projecten falen. De HSL-Zuid en de Noord-Zuidlijn duurden langer om te bouwen dan voorzien en kostten meer dan verwacht. De Betuweroute wordt nog altijd niet zo intensief gebruikt als men verwacht had. De Westerscheldetunnel daarentegen is een succesvol project, in de zin dat het binnen begroting gebouwd is, redelijk op tijd af...conference paper 2011

Hoogenboom, P.C.J. (author), Van Weelden, C. (author), Blom, C.M.B. (author)In this paper stress concentrations are studied around circular cylindrical openings or voids in a linear elastic continuum. The loading is such that a uniform shear stress occurs in the continuum, which is disturbed by the opening. The shear stress is in the direction of the centre axis of the opening. The stress distribution has been...journal article 2010

Meijers, P. (author)In this Delft Cluster work package “Bijzondere Belastingen” (CT01.21) the consequences of an accident with the transport of explosion hazardous goods are considered: BLEVE (Boiling Liquid Expanding Vapour Explosion) and gas explosion. These phenomena have a low probability of occurrence, but might have immense consequences. Therefore, a...report 2009

Molenaar, D.J. (author), Weerheijm, J. (author), Vervuurt, A. (author), Burggraaf, H. (author), Roekaerts, D. (author), Meijers, P. (author)Verkeerstunnels en overkapte wegen (landtunnels) komen de milieukundige en stedenbouwkundige inpassing ten goede en maken meervoudig ruimtegebruik in de stad mogelijk. Het aantal tunnels en overkappingen groeit dan ook. Dit maakt het vervoer van explosiegevaarlijke stoffen en onder hoge druk vervoerde gassen steeds moeilijker, want tankwagens...report 2009

De Rijke, Q.C. (author)Behind the tunnel boring machine (TBM) the rings form a tunnel lining that is embedded in grout and soil. The TBM exerts a normal force, a bending moment and a shear force on the lining. The tunnel rings behind the TBM experience a load through the grout, ground and ground water, but the ground also acts as a support medium. A ring that has just...report 2009

Talmon, A. (author), Bezuijen, A. (author), Hoefsloot, F. (author)Er wordt een eenvoudige methode gegeven om vanuit de groutinjectieverdeling en de grouteigenschappen, de verticale groutdrukgradiënt direct achter de TBM te kwantificeren. Deze groutdrukgradiënt is nodig als input voor de berekening van het krachtenspel in de tunnelbuis tijdens tunnelbouw. Het bestaande gefaseerde analytische liggerwerkingsmodel...report 2007

Mengmeng, X. (author)This first chapter will give an introduction to what is a BLEVE, Boiling Liquid Expanding Vapor Explosion, and its hazards particularly in relation to tunnel safety. It will be shown that several definitions of a BLEVE can be given, depending on the aspect put in focus. In particular distinction can be made between two groups of references,...report 2007

Strack, O.E. (author)The complex variable method for solving two dimensional linearly elastic problems is used to obtain several fundamental analytical solutions of tunneling problems. The method is used to derive the general mathematical representation of problems involving resultant forces on holes in a half-plane. Such problems are encountered in geomechanics...doctoral thesis 2002

Glerum, A. (author)The Netherlands are situated in the delta. of the rivers Rhine, Meuse and Scheldt. Therefore the ground mainly consists.of sediments, such as sand, clay and silt. In certain regions peat layers of varying thickness are found. The high permeability of some of these materials and the fact that the groundwater table is generally only 1 m below...report 1982
