Abstract

BACKGROUND. The paper proposes to solve transportation problems in permafrost conditions using Unitsky String Technologies transport and infrastructure solutions. It is advised to use screw piles to build foundations for structures.

AIM. To ensure safe and efficient transportation of goods and passengers in permafrost areas using string rail systems.

METHODS. Screw piles for support legs of a string rail track structure of transport and infrastructure systems were calculated using Dlubal Rfem software.

RESULTS. The calculation showed high reliability of the proposed design of support foundations.
