ЗАХИСТ ОБ’ЄКТІВ ТРАНСПОРТНОЇ ІНФРАСТРУКТУРИ ВІД ЕЛЕКТРИЧНИХ І ВІБРАЦІЙНИХ ВПЛИВІВ НАЗЕМНОГО РЕЙКОВОГО ТРАНСПОРТУ

Abstract

To decrease the electrical and vibration effects in the city of Kharkov, the tram tracks with rails isolated from the under-rail base with polyurethane composite (embedded rail systems ERS) began to be applied. In order to make to
reduce vibration of ERS and reduce consumption of the composite, special concrete liners were developed. Investigations of the electrical resistance between tram rails and surrounding structures, as well as vibration on surrounding structures, were carried out. It is established that the electrical resistance of ERS is four times higher and the vibrational effect is much lower than these factors for the conventional track.
