Abstract
Ground vibrations due to train traffic on ground surface railways built on soft soil can cause annoyance to people, disturb the function of sensitive machinery in nearby buildings and increase the maintenance costs of the track. At low frequencies (< 20 Hz) the level of vibrations is highly dependent on train weight and speed. This issue must be considered in the design of new railway lines or upgrading old ones. In 1997, shortly after inauguration of the X-2000 high-speed passenger trains between Gothenburg and Malmö in the southern Sweden, extremely high vibration levels were reported in the railway structure, nearby soil and the catenaries at the Ledsgård site and other locations along the newly built ¨West Coast Line¨. In order to mitigate the vibrations and allow the trains to run at their design speed of 200 km/h, soil stabilization using the lime-cement column method was carried out in summer 2000. Measurements before and after the countermeasure showed that, vibrations in the track at maximum speed (200 km/h) were reduced by factor of ten or more. The paper presents the soil stabilization project and some results from the measurements carried out in connection with it.

Mitigation of Train-Induced Ground Vibrations; Lessons from the Ledsgård Project

Ground vibrations due to train traffic on ground surface railways built on soft soil can cause annoyance to people, disturb the function of sensitive machinery in nearby buildings and increase the maintenance costs of the track. At low frequencies (< 20 Hz) the level of vibrations is highly dependent on train weight and speed. This issue must be considered in the design of new railway lines or upgrading old ones. In 1997, shortly after inauguration of the X-2000 high-speed passenger trains between Gothenburg and Malmö in the southern Sweden, extremely high vibration levels were reported in the railway structure, nearby soil and the catenaries at the Ledsgård site and other locations along the newly built ¨West Coast Line¨. In order to mitigate the vibrations and allow the trains to run at their design speed of 200 km/h, soil stabilization using the lime-cement column method was carried out in summer 2000. Measurements before and after the countermeasure showed that, vibrations in the track at maximum speed (200 km/h) were reduced by factor of ten or more. The paper presents the soil stabilization project and some results from the measurements carried out in connection with it.
