TC211 – Bijzondere belastingen in tunnels

The Knowledge Platform for Tunnel Safety (KPT) asked Nils Rosmuller, lecturer in Energy and Transport Safety at the IFV, to think about the possibilities for firefighting in such tunnels. In consultation with Brandweer Nederland, Rijkswaterstaat and the IFV  Brandweeracademie, resources for officers-in-charge have been developed. This document presents the tools that have been developed (decision diagram and operational capability table) as well as the process of their creation and ideas about the section on 'concrete spalling' in the development of the decision diagram. 

On 8 August 2017, the Minister of Infrastructure and Water Management sent a letter to the Dutch House of Representatives concerning the reduced fire resistance of concrete in four tunnels as established following an investigation by Rijkswaterstaat. This received extensive media attention and the findings led to many questions from various interested parties. This publication contains an overview of the results obtained through a collaborative process of those interested parties, facilitated by the Knowledge Platform for Tunnel Safety (KPT).

Research commissioned by Rijkswaterstaat has shown that the fire resistance of tunnels made of ROK concrete may be impaired. In response to this, four discussion tables were set up at the end of 2017 under the coordination of the Knowledge Platform for Tunnel Safety (KPT) with the aim of discussing the problems outlined above from various perspectives. These are the discussion tables for Existing Tunnels, New Tunnels, Research, and Emergency Services.  This document was prepared by Discussion Table - Research in response to the request for further substantiation of the final conclusions. The explanations presented here basically reflect the way in which each conclusion was reached and the reasons for it. The conclusions (and the explanations) should, however, be considered as a whole, in view of the order in which they are reached and to safeguard the message.

Dit afstudeerwerk biedt een vernieuwende visie ten aanzien van de brandwerendheid van betonnen tunnels.

In dit project is onderzocht hoe een tunnelbeheerder gefundeerd en afgewogen besluiten kan nemen over de instandhouding van de veiligheid van zijn tunnel. Een belangrijke constatering hierbij is dat het onderzoeksresultaat overeenkomt met de verwachtingen van het projectteam.

Het Delft Clusterprogramma was opgezet om de ontwikkeling en verspreiding van kennis voor de grond-, weg- en waterbouwsector te bevorderen, met als belangrijkste punten infrastructuur en water. Het programma is inmiddels afgerond, maar alle voor de geotechniek relevante producten zijn terug te vinden op deze pagina.
