Investigation of JGS frost susceptibility testing method

Abstract

Abstract Frost heave is a type of frost action that occurs when the soil temperature is below freezing temperature. Construction in cold regions is challenging and can cause severe damage to structures due to frost heave. The segregation potential (SP) is widely accepted in engineering design and for frost heave predictions as an indicator for frost susceptibility classification. The purpose of this study is to investigate the frost heave experiments in the JGS method and to evaluate the JGS frost susceptibility testing results for different soil mixtures with different SP through numerical simulation with a Thermal-Hydraulic coupled model. The results show good agreement between numerical simulation and test results for different degrees of frostsusceptible soils. This model is expected to provide accurate predictions of the frost heave behavior of different soils.
