11. Railway Track Stiffness : Dynamic Measurements and Evaluation for Efficient Maintenance
Sammanfattning : Railway track stiffness (vertical track load divided by track deflection) is a basic parameter oftrack design which influences the bearing capacity, the dynamic behaviour of passing vehiclesand, in particular, track geometry quality and the life of track components. Track stiffness is abroad topic and in this thesis some aspects are treated comprehensively. LÄS MER
12. Soil identification by vibration measurements during soil-rock sounding
Sammanfattning : Dynamic penetration tests are frequently used as geotechnical site investigation methods. In Sweden, the main reason to choose a dynamic penetration method is to investigatedepth to bedrock, strength and deformation properties of soil, compaction, or pilingdepth. LÄS MER

Sammanfattning : .... LÄS MER
14. Ground vibrations due to pile and sheet pile driving : influencing factors, predictions and measurements
Sammanfattning : Ground vibrations due to pile driving are part of a complex process. Vibration is generated from the pile driver to the pile. As the pile interacts with the surrounding soil, vibrations are transferred at the pile-soil interface. The vibration propagates through the ground and interacts with structures, both above ground and underground. LÄS MER
15. On Ground and Structural Vibrations Related to Railway Traffic
Sammanfattning : The continuous development and integration of railway infrastructure, especially within urban areas, can cause ground and building vibrations to reach levels that bring discomfort to people. The growing risk of damage to buildings located in areas prone to ground vibration should not be underestimated. LÄS MER
