Abstract
The ground deformation analysis that takes account of frost heave ratios based on the experimental formula, is proposed to seek for a countermeasure against the expansive displacement caused by the freezing method. The frost heave ratios of each area divided according to the heat flow direction, are calculated by two models considering the cooling surface shape, and this method is incorporated with the three-dimensional elastic FEM.
The validity of this method is confirmed by the measurements in two sites, of which installation direction of the freezing pipes are different. Moreover, the effectiveness of this analysis is verified by comparison with the cases assuming the one-dimensional and the isotropic frost expansions.
