1. 6. Soil-structure interaction of end-frames for high-speed railway bridges

   Master-uppsats, KTH/Bro- och stålbyggnad

   Författare :Johan Östlund; [2016]
   Nyckelord :Dynamics; SSI; Soil-structure interaction; Soil-bridge interaction; HSR; High-speed railway; Impedance; Receptance; End-frame bridge; Dynamik; SSI; Jord-struktur interaktion; Jord-bro interaktion; HSR; Höghastighetsbana; Höghastighetståg; Impedans; Receptans; Ändskärmsbro;

   Sammanfattning : In this thesis, the influence of soil-structure interaction (SSI) of end-frame bridges for high-speed railways was studied. Impedance functions, representing the SSI, was calculated and analyzed. The impedance functions were applied to end-frame bridge models which were analyzed for use in HSR. LÄS MER

3. 7. Besiktning av järnvägsanläggningar - Alternativa besiktningsmetoder vid järnvägen

   Kandidat-uppsats, Lunds universitet/Utbildningar i Helsingborg

   Författare :Britt-Marie Thomasson; John Axelsson; [2013]
   Nyckelord :järnväg; besiktning; tidseffektiv; kostnadseffektiv railway; railway inspection; time-efficient; cost-efficient; Technology and Engineering;

   Sammanfattning : The traffic has increased, leaving less time for inspection of the railway system. With the increased freight- and passenger traffic in the Malmö area the wear of railway infrastructure also increase. As traffic has increased, the space for the inspection of the railway system has decreased, making it difficult for inspectors to do their work. LÄS MER
