โœฆ Synopsis

Due to Swiss environmental legislation, the Swiss Federal Railways (SBB) has to minimize the negative influences of vibration in buildings near railways. For every newly constructed or extended railway track, costly measurements and calculations have to be undertaken to assess future immissions of vibration and structure-borne noise. To predict such immissions and determine corresponding measures in a less expensive and simpler manner, a three-part computer program (VIBRA 1-2-3) was developed. VIBRA-1 is a relatively simple, semi-empirical calculation model to identify problem areas. VIBRA-2 is a much more complex and detailed program, including most of the important factors influencing immissions. VIBRA-3 is the database containing measurements of vibration and structure-borne noise immissions, supplying the basic parameters for the models in VIBRA-1 and VIBRA-2. These three programs and their application are discussed.

The social pressure to decrease noise nuisance caused by rail transport lines is growing rapidly. The solutions realized by the railway companies are often only effective locally and are specified without taking note of future European transport flows. In order to evolve their new policy the Dutch R
