| Abstract | Frost heave along Canadian railways is a common issue that can result in track geometry issues and reductions in train speeds and rail traffic capacity. This study was conducted at a location prone to frost heave on VIA Rail Canada’s Smith Falls subdivision to determine the maximum frost penetration depth at this site during the last 20 years and explore a correlation between frost depth and weather conditions for future anticipation of frost depth. The results include frost depth fluctuations over the last 20 winters using a thermal analysis conducted by TEMP/W, a regression between weather data and frost penetration depth, and predicted frost depth for the next 75 years based on a high greenhouse gas climate model. The results showed that frost depths estimated using conventional methods and numerical analysis were significantly different and the maximum frost depth tends to decrease in the future but it will be within the frost susceptible layers and could still be problematic at this site. So further monitoring or actions might be needed to prevent frost heave and consequent thaw softening at this location. |
