System ciągłego monitorowania drgań w metrze warszawskim jako przykład redukcji emisji do środowiska

Abstrakt

"The launch of the first finish line in Warsaw was a great event that significantly alleviated the capital's traffic problems, but it also
resulted in the emergence of new problems. One of them is the vibrations produced by passing trains in the tunnel next to residential
buildings. The problem appeared ""with some delay"", after approximately two years of operation of the new Metropolis type wagons
(previously only Russian-made wagons were used). The residents of Niepodległości street were the first to find out about it. There
where after a series of articles in the local press there was a need to identify the cause of the troublesome vibrations. The basis for all
assessments and analyzes of the impact of vibrations on buildings and people staying in them are vibration measurements carried out
appropriately. Also, forecasts of such impacts and assessment of the environmental impacts of dynamic investments depend on the
results obtained from vibration measurements carried out ad hoc in a given case or collected in measurement databases. Thus, the
results of monitoring the impact of vibrations on the environment, the results of the above-mentioned assessments and analyzes are
significantly dependent on the reliability of the results obtained from vibration measurements. Obtaining reliable measurement results
requires the use of specialized equipment for measuring building vibrations in the low-frequency range, and those performing such
measurements should have specialized knowledge and experience in performing vibration measurements in buildings. The aim of the
research was to determine the impact of metro trains on buildings located in Warsaw at Niepodległości street together with an
assessment of these impacts on buildings and especially people in buildings. In this publication, the author presented the results of his
own research conducted over the years in the Warsaw metro, as well as the origins and selected results of the continuous vibration
monitoring system implemented in the Warsaw metro."
