Sammanfattning : Conceptual design is the first phase in the design process in which all the requirements and design objectives are synthesized into conceptual alternatives. In practice today, major decisions regarding the buildings function, massing, and overall form are usually made during the first phase. LÄS MER
Sammanfattning : Banverket is expecting that the number of railway tunnels in densely populated areas will increase over the next 20 years due to the lack of available space on the ground surface, but also since the railway is considered an environmentally friendly solution of transportation for the future. The need for good predictions of vibration and noise levels in dwellings along the planned tunnels is therefore evident. LÄS MER
3. Prediction and experimental validation of dynamic soil-structure interaction of an end-bearing pile foundation in soft clay
Sammanfattning : In the built environment, human activities such as railway and road traffic, constructionworks or industrial manufacturing can give rise to ground borne vibrations. Such vibrations become a concern in urban areas as they can cause human discomfort or disruption of vibration sensitive equipment in buildings. LÄS MER
Sammanfattning : The primary objective of the thesis has been to extend the capabilities for computational modeling, prediction and simulation of the elastic response of the train, track structure and soil in railway systems. The industrial background is the high level of ground borne vibrations reported from citizens as a consequence of train traffic (in particular from high speed trains) in several Swedish locations.

Sammanfattning : This thesis concerns wave propagation in rock as a tool for determination of rockproperties and as a consequence of activities, such as trains.Using waves as a tool often means that rock properties are determined or the interior of a sample is studied without being damaged. LÄS MER
