  The problems encountered during the analyzes of structural response of historic masonry railroad arch bridges are described in this paper. The attention is mainly focused on the stiffness of the masonry arches, their strengths and appropriate estimation of railroad load intensity. Issues related to computational modelling of two, existing, almost 130 years old masonry arch railroad bridges are presented in this context. The main...

  - Year 2021

  There were 12801 road through railroad one-level crossings in Poland in 2018. 215 accidents happened at them in 2018. In order to increase safety in rail and road traffic two-level crossings should be used. They are definitely safer and make the traffic more smooth. In the design and construction of two-level intersections of railway and road or path columns of circular cross-section are often used. They can be successfully replaced...

  - Year 2006

  Przedstawiono wyniki symulacji numerycznej oraz pomiarów parametrów anteny tubowej z podwójnym grzbietem. Badania numeryczne dotyczyły zarówno samego układu zasilania falowodu grzbietowego jak i całej anteny z uwzględnieniem sinusoidalnego profilu impedancji grzbietu. Wyniki obliczeń dopasowania oraz charakterystyk promieniowania, wykonanych przy użyciu symulatora QW-3D, porównano z wynikami pomiarów, stwierdzając dobrą zgodność...

  - SCIENCE OF THE TOTAL ENVIRONMENT - Year 2021

  Soil samples from cut slopes from lightly loaded railway lines used by Diesel Multiple Units for 5 years in Gdansk (Poland) were collected and analyzed for trace metals (TMs): Zn, Pb, Cd, Ni, Cr, Cu, and Fe. The main aim was to assess soil enrichment, contamination status, and distribution of TMs relative to the distance from the railway track. Extensive source tracking analyses were performed using cluster analysis (CA) and the...

• Application of the Polish active GNSS geodetic network for surveying and design of the railroad

  Publication

  - Year 2010

  W pracy przedstawiono opis sieci ASG-EUPOS oraz architekturę zastosowanego zestawu pomiarowego GNSS. Opisano geodezyjne przygotowanie pomiarów toru kolejowego, które przeprowadzono na ok. 30-kilometrowym odcinku testowym. Ustawienie centrów fazowych anten względem osi toru testowego wyznaczono metodami geodezji tradycyjnej w oparciu o pomiary tachimetryczne. Na podstawie przeprowadzonych pomiarów ksztaltu geometrycznego toru podjęto...
