Abstract (en)
The subject of the doctoral dissertation is the impact of railway traffic on
the environment, with the aim of preventing/mitigating water and soil
pollution in the area of railway tracks. Through a detailed analysis of the
prescribed technical conditions for the design of railway substructure
elements, the basic requirements were determined, which conditioned the
proposal of new solutions related to the substructure. An independent
investigation of the material in the railway body was carried out regarding
the presence of heavy metals. For research purposes, two methods were
used, optical emission spectrometry with induced coupled plasma (ICPOES)
and X-ray fluorescence spectrometry (XRF). Since it was confirmed
that there is a significant amount of heavy metal particles in the railway
body, the proposal of contemporary solutions for drainage channels and
elements in the railway body itself was approached in order to prevent the
release of heavy metals into the surrounding soil and environment. The
proposed solution included the replacement of conventional drainage
ditches with infiltration channels. In this regard, experimental testing of the
filter properties of four types of filters was carried out. The efficiency of
the proposed filters was verified using the ICP-OES technique, and the
filter with river aggregate of fraction 4 – 8 mm was identified as the most
efficient. The hydraulic parameters of the route case with typical (drainage)
ditches and the route case with the proposed infiltration channels were
evaluated by SWMM software. The modeling results revealed that using
infiltration channels does not result in the total utilization of the drainage
components' capacity, which improves railway safety in terms of floods.
