Cross-Sectional Temperature Analysis of Slab Track Taking Solar Radiation into Account for Predicting Frost Damage

Abstract

In some cold regions, the freezing and thawing action has caused frost damage to the slab track filling layer. For the purpose of predicting frost damage to slab track, we proposed a temperature prediction method based on a coupled analysis of solar radiation and heat conduction, taking into account the shading of railway structures such as sound barriers. By applying corrections to the proposed method to simulate the effects of snow accumulation and other factors in concave areas, we were able to reproduce the actual temperature of the slab track cross section.
