Opis (srp)

The subject of the doctoral dissertation is the impact of railway traffic onthe environment, with the aim of preventing/mitigating water and soilpollution in the area of railway tracks. Through a detailed analysis of theprescribed technical conditions for the design of railway substructureelements, the basic requirements were determined, which conditioned theproposal of new solutions related to the substructure. An independentinvestigation of the material in the railway body was carried out regardingthe presence of heavy metals. For research purposes, two methods wereused, optical emission spectrometry with induced coupled plasma (ICPOES)and X-ray fluorescence spectrometry (XRF). Since it was confirmedthat there is a significant amount of heavy metal particles in the railwaybody, the proposal of contemporary solutions for drainage channels andelements in the railway body itself was approached in order to prevent therelease of heavy metals into the surrounding soil and environment. Theproposed solution included the replacement of conventional drainageditches with infiltration channels. In this regard, experimental testing of thefilter properties of four types of filters was carried out. The efficiency ofthe proposed filters was verified using the ICP-OES technique, and thefilter with river aggregate of fraction 4 – 8 mm was identified as the mostefficient. The hydraulic parameters of the route case with typical (drainage)ditches and the route case with the proposed infiltration channels wereevaluated by SWMM software. The modeling results revealed that usinginfiltration channels does not result in the total utilization of the drainagecomponents' capacity, which improves railway safety in terms of floods.
