2. 1. Rail Tunnel Evacuation

   Author : Karl Fridolf; Avdelningen för Brandteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smoke; walking speed; flow rate of people; experiment; train; tunnel; metro; underground rail transportation system; evacuation; Human behavior in fire;

   Abstract : In this thesis, human behavior in rail tunnel fires is explored. Descriptive knowledge is presented related to the evacuation of passenger trains, and the subsequent tunnel evacuation to a safe location. READ MORE

4. 2. Durability of fire exposed concrete : Experimental Studies Focusing on Sti„ffness & Transport Properties

   Author : Joakim Albrektsson; Johan Silfwerbrand; Lars Boström; Manouchehr Hassanzadeh; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; Fire; Polypropylene fibres; Durability; Tunnel; Damage assessment; Ultrasonic pulse velocity; Water absorption; Chloride migration; DIC; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : Road and rail tunnels are important parts of the modern infrastructure. High strength concrete (HSC) is commonly used for tunnels and other civil engineering structures, since it allows high load carrying capacity and long service life. In general, Swedish road and rail tunnels should be designed for a service life of 120 years. READ MORE

   Abstract : Important phenomena related to tunnel fires are presented including both experimental and theoretical work. The main focus is on the large-scale fire tests performed in 2003, in the Runehamar tunnel in Norway. READ MORE

6. 4. Design fires in underground hard rock mines

   Author : Rickard Hansen; Haukur Ingason; Håkan Frantzich; Mälardalens högskola; []
   Keywords : Design fire; underground; hard rock mine; vehicle fire; smoke spread; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : During several decades considerable research activities have been conducted with respect to fires in coal mines, but the research activities with respect to hard rock mines have been limited. As the hard rock mines are getting more complex the need for deeper understanding of fires in underground hard rock mines are getting more in demand. READ MORE

7. 5. Fire safety design of road tunnels

   Author : Jonatan Gehandler; Avdelningen för Brandteknik; []
   Keywords : HUMANIORA; HUMANITIES; Brandsäkerhet; vägtunnlar; design; Riskbedömning; Road tunnel fire safety; Fire safety engineering; design framework; risk evaluation;

   Abstract : This thesis can be described as a journey in performance-based fire safety design. Along the way questions such as what fire safety is, how it can be measured, whether we are posing the right questions, or engineer the best solutions, have arisen. READ MORE
