1. Norms and legal rules : An investigation of the tunnel construction through the Hallandsås ridge
Sammanfattning : In 1992 Swedens biggest tunnelproject begun. Two 8.5 km tunnels should cross a big ridge in southern Sweden which was seen as an obstacle to a fast and efficient railway line connecting Oslo and Gothenburg with Malmö and Copenhagen. However, the project had to stop in 1997 due to environmental damages. LÄS MER
2. Drill process monitoring in percussive drilling for location of structural features, lithological boundaries and rock properties, and for drill productivity evaluation
Sammanfattning : This thesis deals with the application of percussive drill monitoring in the mining and underground construction industries. The technique has been used to provide information on different ground properties and conditions and for drill productivity evaluation. LÄS MER
3. Advances in time–domain induced polarisation tomography : Data acquisition, processing and modelling
Sammanfattning : What would you find below your feet – how do you find out? Perhaps you could look at a geological map, drill, or dig? That could work, but sometimes the maps are not detailed enough, and digging everywhere to find out is impractical. Imagine if you could develop a method that allows you to see straight through the ground, as x–rays through the body! To some extent, such methods already exist; you can for example send electric current into the ground that tells you what lies beneath when it returns. LÄS MER
4. From Green Image to Green Practice : Normative action and self-regulation
Sammanfattning : Ever since environmental issues appeared on the agenda of modern industrial society, through the work of whistle blowers such as Rachel Carson, Georg Borgström, Björn Gillberg and Hans Palmstierna, the Swedish state has exerted itself to project a green image. In practice this image has merely functioned as a defence for the legitimacy of industrial development. LÄS MER
5. Groundwater chemistry affected by underground construction activities
Sammanfattning : A leaking underground construction increases the groundwater recharge and decreases the residence time of the groundwater. If groundwater of a certain chemical composition dominated the location inside the bedrock of a planned tunnel prior to the construction phase, this water is likely to be replaced by water of a different chemical type because of leakage of water into the tunnel during the construction and operational phases.
