| Abstract: | Frost heave is one of the main freezing problems for construction in permafrost regions. The Konrad-Morgenstern segregationpotential (SP) model is being used in practice for frost heave using numerical techniques. However, the heat releasefrom in-situ and migrated water in the freezing zone could result in some numerical instability, so the simulation offrost fringe is not ideal. In this study, a semi-analytical solution is developed for frost heave prediction of clay soil. Theprediction results to the two tests with different freezing mode with clay soil agree well with the tested behavior, whichindicates the feasibility of the solution. |
