The article describes the reasons for the need to compensate for changes in the length of floating bridges from several sets of NZHM-56 (MLZH-VF-VT). A constructive solution of the coastal part of the bridge NZHM-56 is proposed, providing a change in the necessary limits of the distance between the crossing ferries for the purpose of unhindered output and input of the output ferry at significant temperature changes in the river part.

COMPENSATION OF ROLL OF FLOATING RAILWAY BRIDGE AT HIGH RIVER FLOW RATES

Author:

Sergei Zavalnuk

The article describes the causes of the roll of floating railway bridges, as well as the need for its compliance with the regulatory requirements of railway transport. Constructive (technical) solutions for floating railway bridges are given, which reduce the amount of roll and increase the safety of passing trains at high speed of the river flow.
