Abstract

The stability of permafrost subgrade is an important guarantee for the safe operation of vehicles in permafrost regions. The main factors that affect the stability of roadbed are the change of temperature field of subgrade, surface water on both sides of subgrade and groundwater (frozen water, frozen inter-layer water) and the amount of ice in formation, that is, the strength of protective measures of permafrost hydrothermal influence. The principle of preventing and controlling the stability of permafrost subgrade is to control the temperature field of permafrost subgrade. According to the theory of heat transfer, controlling the radiation, regulating convection and regulating and controlling can effectively control the subgrade temperature field. Board, set the insulation layer, buried hot rod, set the ventilation pipe, riprap embankment, variable thermal conductivity coefficient of materials, insulation materials and other measures. At this stage, there are many stability measures, but there are few advantages and disadvantages of the measures. This article mainly analyzes three main control measures of installing insulation, embedding hot rods and setting ventilation pipes, and analyzes their working mechanism and compares the advantages and disadvantages for a brief.
