1. 1. Constructing Safety: Influence of Safety Climate and Psychological Climate on Safety Behaviour in Construction Industry

   Författare :Susanna Larsson; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; safety performance; safety climate; organisational climate; construction industry; safety behaviour; occuopational safety; accident prevention; psychological climate;

   Sammanfattning : Although, significant progress has been made in improving occupational safety in construction industry the number of deaths and injuries are still unacceptably high. In the recent years, extensive research on safety climate, part of the organisational climate research body, has been perfromed. LÄS MER

3. 2. Fire safety design of road tunnels

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

   Sammanfattning : 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. LÄS MER

4. 3. Influence of heat on the physical and mechanical properties of selected rock types

   Författare :Christine Saiang; Karl-Johan Loorents; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tunnel fires; heat influences; temperature increase; mechanical properties; physical properties; micro cracks; mineralogy; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Sammanfattning : Impelled by the increase in the number of tunnel fires in the last decade alone, wide spread attention has been drawn towards tunnel fire safety studies. Many of these fires occurred in road and railway tunnels involving vehicles and trains. LÄS MER

5. 4. Emissions from Fires Consequences for Human Safety and the Environment

   Författare :Per Blomqvist; Avdelningen för Brandteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kontroll av utsläpp; pollution control; Miljöteknik; Environmental technology; Byggnadsteknik; Building construction; incapacitation; CFD; simulations; emissions; particles; dioxin; PAH; gases; quantitative analysis; fire effluents; chemical characterisation; large-scale experiments;

   Sammanfattning : Accidental fires represent a risk for people from the heat and fire effluents produced. It is clear from fire statistics that it is, in fact, the toxic gases that kill and injure many fire victims. Further, there are a number of compounds that are readily produced in fires, which have important sublethal effects on humans. LÄS MER

7. 5. Effects of deep excavations in soft clay on the immediate sourroundings-Analysis of the possibility to predict deformations and reactions against the retaining system

   Författare :Anders Kullingsjö; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIT-S1; Sheet pile wall; Soil-structure interaction; Strain; Stress; Ground surface settlement; Finite element method; Case history; Shear test; Shear strength; Pore pressure; Analysis; Constitutive models; Plane strain; Elastoplasticity; Laboratory tests; Factor of safety; Stiffness; e-ADP; Earth pressure; Anisotropy; Soft Clay; Deep excavation; Retaining wall; Shear stress; Deformation;

   Sammanfattning : When excavating in an urban environment, the evaluation of the magnitude and distribution of ground movements is an important part of the design process, since excessive movements can damage adjacent buildings and utilities. In order to minimize movement of the surrounding soil, a retaining wall support system is used for deep excavations to provide lateral support. LÄS MER
