1. Undifferenced GPS for Deformation Monitoring
Sammanfattning : This thesis contains the development of a deformation monitoring software based on undifferenced GPS observations. Software like this can be used in alarm systems placed in areas where the earth is unstable. LÄS MER
2. Automated performance monitoring of concrete dams
Sammanfattning : The Swedish hydropower industry operates a large number of power plants and dams geographically spread over the country. The level of safety of a specific dam is to a large extent determined during the design and construction phases that in the case of Swedish hydropower plants took place several decades ago. LÄS MER
3. Deformation and failure of rock
Sammanfattning : In this doctoral thesis work the relationship between the deformation and the initiation of failure around an underground excavation was studied. In this work data from observed failure and measured deformations was used. This work is based on information obtained from laboratory test, underground field cases and numerical analysis. LÄS MER
4. Towards Model-Based Condition Monitoring of Railway Switches and Crossings
Sammanfattning : Railway switches and crossings (S&C, turnouts) connect different track sections and create a railway network by allowing for trains to change between tracks. This functionality comes at a cost as the load-inducing rail discontinuities in the switch and crossing panels cause much higher degradation rates for S&C compared to regular plain line track.

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
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
